Heap of Jewels

The Chapter Teaching the Purification of Boundless Gateways consists of an extended discourse presented by the Buddha to his bodhisattva disciple Anantavyūha. The instruction consists of a so-called dhāraṇī gateway, a teaching that involves a series of dhāraṇī spells, which are interspersed throughout. The teaching is generally concerned with well-known Mahāyāna Buddhist themes, ranging from the lack of inherent identity to the qualities of complete awakening, but these topics are here presented within a larger exegesis on the meaning of the dhāraṇī gateway.

Teaching the Unfathomable Secrets of the Tathāgatas is a fascinating third turning mahayāna sūtra extracted from the larger Ratnakūṭa sūtra that explores a diversity of topics across 24 chapters and an epilogue.

Both the Buddha and Vajrapāṇi teach, discussing the secrets of the body, speech, and mind of the bodhisattvas and the buddhas, nonduality, the relationship of the nature of mind to the qualities of buddhas and bodhisattvas, and other subjects. It follows a consistently nondual perspective ‍— identifying that while an awakened being may seem to be engaged in a conceptual or dualistic action, they never leave the scope of nonconceptual wisdom. It reveals the extraordinary freedom that awakened beings have in their acting in the world.

The Teaching of the Armor Array describes a dialog between the Buddha Śākyamuni and the bodhisattva Anantamati. The sūtra is primarily concerned with the great armor, a quality related to the perfection of insight. As such, it is no conventional sort of armor. Rather, donning it involves giving up all grasping at phenomena, and engaging diligently on the path, with insight into the nature of phenomena. The Buddha and Anantamati also discuss the nature of the Great Vehicle and the great path, all the while emphasizing their emptiness and lack of marks.

While the Buddha is in the Jeta Grove, he asks Mañjuśrī to teach on the nature of reality. Mañjuśrī’s account upsets some of the monks present in the gathering, who subsequently leave. Nevertheless, by means of an emanation, Mañjuśrī skillfully teaches the distraught monks, who return to the Jeta Grove to express their gratitude. The monks explain that their obstacle has been a conceited sense of attainment, of which they are now free. At the request of the god Ratnavara, Mañjuśrī then teaches on nonduality and the nature of the bodhisattva. Next, the Buddha prophesies the future awakening of Ratnavara and other bodhisattvas present in the gathering. However, the prophecies cause Pāpīyān, king of the māras, to appear with his army. In a dramatic course of events, Mañjuśrī uses his transformative power on both Pāpīyān and the Buddha’s pious attendant, Śāradvatīputra, forcing both of them to appear in the form of the Buddha himself. He then makes Pāpīyān and Śāradvatīputra teach the profound Dharma with the perfect mastery of buddhahood. Numerous bodhisattvas appear from the four directions, pledging to practice and uphold the sūtra’s teaching. The Buddha grants his blessing for the continuous transmission of the sūtra among bodhisattvas in the future.

In The Exposition on the Universal Gateway, the bodhisattva Amalagarbha arrives in this world from a distant pure land to request teachings from the buddha Śākyamuni. The Buddha proceeds to explain to all assembled bodhisattvas, monks, and lay devotees the manner in which the five aggregates are equal to meditative absorption. He also explains how the various classes of beings and all other phenomena are absorption as well. In conclusion, he lists the names of various absorptions and the benefits one obtains upon attaining these states.

An important sūtra from the Ratnakuta (“Heap of Jewels”) collection that sets out in detail the stages and practices of the path of the Bodhisattva vehicle. It contains extensive explanations on key Mahāyāna practices, including the Four Immeasurable Thoughts, Six Perfections, and more.

In The Teaching to Venerable Nanda on Entry into the Womb, the Buddha gives a detailed account to his half-brother Nanda of the thirty-eight weeks of human gestation. The sūtra explains conception in terms of how the antarābhava (the being in the state between death in one life and birth in the next) enters the womb, and details the physical composition of the embryo, the suffering of the newborn being, and the miseries experienced over the course of a lifetime. Including as it does the most comprehensive ancient Indian account of gestation, it was an important source for embryology in Tibetan medicine.

In this sūtra, the Buddha Śākyamuni explains the connection between the bodhisattvas’ aspirations and the virtues of their future buddha realms. He describes the various qualities that help bodhisattvas bring their aspirations to fulfillment. After bodhisattvas arrive from all directions to hear his teachings on the virtues of the buddha realms, the Buddha Śākyamuni recounts the story of how Mañjuśrī first engendered the mind set on awakening. Finally, the Buddha reveals the extraordinary nature of Mañjuśrī’s bodhisattva aspirations, and how they will contribute to the exceptional qualities of his future buddha realm.

In Veṇuvana, outside Rājagṛha, Pūrṇa Maitrāyaṇīputra asks the Buddha about the conduct of bodhisattvas practicing on the path to awakening. The Buddha replies by describing the attitudes that bodhisattvas must possess as well as their benefits. Then, at the request of Maudgalyāyana, the Buddha recounts several of his past lives in which he himself practiced bodhisattva conduct. At the end of the teaching, the Buddha instructs the assembly about how to deal with specific objections to his teachings that outsiders might raise after he himself has passed into nirvāṇa.

The newly ordained monk Rāṣṭrapāla questions the Buddha about the proper conduct of a bodhisattva. The Buddha proceeds to explain its features in detail, giving as examples his own conduct in his multiple past lives. He tells the story of his past life as prince Puṇyaraśmi, who abandoned pleasure, a kingdom, and riches to follow the bodhisattva path to enlightenment for the sake of sentient beings.

Ascertaining the Vinaya: Upāli’s Questions is a sūtra focused on the relationship between and integration of the prātimokṣa vows of monastic discipline and the conduct of a bodhisattva who follows the Mahāyāna tradition. The sūtra’s two main interlocutors, Śāriputra and Upāli, query the Buddha about the relationship between these two levels of commitments, eliciting a teaching on the different orientations held by the followers of different Buddhist vehicles and how their different views affect the application of their vows. Ascertaining the Vinaya is a particularly valuable sūtra for its inclusion of a unique form of the confessional “Three Sections” rite, making it one of the few extant canonical sources to describe it at length.

Inspiring Determination is directed at reforming the conduct of sixty bodhisattvas who have lost their sense of purpose and confidence in their ability to practice the Dharma. The bodhisattva Maitreya leads them to seek counsel from the Buddha, who explains the causes these bodhisattvas created in former lives that resulted in their current circumstance. They make a commitment to change their ways, which pleases the Buddha, and this leads him to engage in a dialog with the bodhisattva Maitreya on how bodhisattvas, including those in the future age of final degeneration, the final half-millennium, should avoid faults and uphold conduct that accords with the Dharma.

In this scripture Śākyamuni Buddha describes how a bodhisattva should ideally train in the six perfections. In the Veṇuvana near Rājagṛha, the Buddha teaches this sūtra in response to a single question put to him by the bodhisattva Subāhu: what are the qualities a bodhisattva should have in order to progress to perfect awakening? The Buddha responds by first listing the six perfections of generosity, ethical discipline, patience, diligence, concentration, and insight, and then expounding in greater detail on each perfection in turn.

Surata's Questions follows Surata, a seemingly poor vagabond endowed with a wealth of ethical virtue. The juxtaposition of Surata’s poverty with the abundance of his moral merits forms a central theme of the sūtra. After being tested by the god Śakra, Surata finds a precious gem that he decides to give to the poorest person in the city. The narrative’s irony ensues when Surata decides that King Prasenajit should receive the gem, since his ethical depravity vitiates his material wealth. The shock of Surata’s decision occasions a valuable lesson on true wealth lying in moral integrity, to which the Buddha himself attests upon his arrival midway through the sūtra. The sūtra concludes with King Prasenajit’s recognition of the error of his ways and the Buddha’s prophecy of Surata’s coming awakening.

In The Questions of Guṇaratnasaṅkusumita, the sūtra’s interlocutor, Guṇaratnasaṅkusumita, asks the Buddha Śākyamuni whether there might be other buddhas in other realms whose names carry the power to produce awakening. The Buddha responds that there are, in fact, buddhas whose names are so efficacious that simply by remembering them, the disciple will be awakened. The Buddha then names the buddhas of the ten directions, their worlds and eons, and the specific effects that knowing each of their names will have on disciples with faith.

In The Questions of Bhadrapāla the Merchant, the Buddha’s principal interlocutor is a wealthy merchant who asks him to explain what consciousness is, and what happens to it when one dies and is reborn. In his characterization of consciousness, the Buddha relies heavily on the use of analogies drawn from nature. The sūtra also reflects common cultural beliefs of ancient India, such as spirit possession. In addition, it presents graphic and vividly contrasting descriptions of rebirth in the realms of the gods for those who have lived meritorious lives and in the realms of hell for those who lack merit.

Vimalaśraddhā, the daughter of King Prasenajit, comes to see the Buddha in Jetavana, together with a retinue of five hundred women. She pays homage to the Buddha and asks him to explain the conduct of bodhisattvas. The Buddha responds by presenting twelve sets of eight qualities that bodhisattvas should cultivate. Vimalaśraddhā and her five hundred companions, having developed the mind set on awakening, join the ranks of the bodhisattvas, and the Buddha prophesies her future attainment of awakening.

In The Question of Maitreya, the bodhisattva Maitreya asks the Buddha what qualities a bodhisattva needs to attain enlightenment quickly. The Buddha outlines several sets of qualities, foremost among them the altruistic intention of perfect bodhicitta. The Buddha then recounts to Ānanda how, in a former life, Maitreya revered a previous Buddha and, wishing to become just like him, at once realized that all phenomena are unproduced. Ānanda asks why Maitreya did not become a buddha sooner, and in answer the Buddha compares Maitreya’s bodhisattva career with his own, listing further sets of qualities that differentiate them and recounting examples of the hardships he himself faced in previous lives. Maitreya, on the other hand, has followed the easy bodhisattva vehicle using its skillful means, such as the seven branch practice and the training in the six perfections; the aspirations he thus made are set out in the famous “Prayer of Maitreya” for which this sūtra is perhaps best known. The Buddha declares that Maitreya will become enlightened when sentient beings have fewer negative emotions, in contrast to the ignorant and turbulent beings he himself vowed to help.

In The Question of Maitreya on the Eight Qualities, Maitreya asks the Buddha what qualities bodhisattvas need in order to be sure of completing the path to buddhahood. In response, the Buddha briefly lists eight qualities. Starting with the excellent intention to become enlightened, they include loving kindness, as well as realization of the perfection of wisdom, which the Buddha explains in terms of reflection on the twelve links of dependent origination.
