The
Ratnacūḍaparipṛcchā ("The Questions of Ratnacūḍa," Tib.
dkon mchog brtsegs pa) is a
Mahāyāna sūtra preserved in the Tibetan Kangyur (D 91, dkon brtsegs, cha 210a1–254b7, vol. 44) as part of the Ratnakūṭa collection of
sūtras. The text is cited extensively by Śāntideva in the
Śikṣāsamuccaya, where it appears under the abbreviated title
Ratnacūḍasūtra ("
Sūtra on the Jewel at the Crown of the Head"), most prominently in Chapter 13, which is devoted to the four applications of
mindfulness (
smṛtyupasthāna). In that chapter the text is cited in connection with each of the four applications in turn. On the application of mindfulness to the body, it teaches that the body is impermanent and ends in death, and that those who truly understand this become servants of all sentient beings, avoid crookedness and hypocrisy, and give up clinging to possessions; it further teaches that the
bodhisattva connects the bodies of all sentient beings to his own, aspiring that all beings attain the body of a Buddha. On the application of mindfulness to feelings, it teaches that
bodhisattvas cultivate
great compassion for beings caught in pleasant, painful, and neutral feelings, giving up the underlying tendencies to attraction,
aversion, and delusion respectively, while experiencing all feelings as impermanent, as suffering, and as without self. On the application of mindfulness to mind, it addresses the impossibility of locating mind internally, externally, in the aggregates, components, or sense-spheres, using the analogy that mind cannot perceive itself just as a sword cannot cut itself. On the application of mindfulness to phenomena (dharma), it teaches that when bodhisattvas look at phenomena they see no phenomena at all—no arising without a cause, and no producer—and that they never give up the
recollection of the mind of awakening no matter how deeply they look into the teachings. The abbreviated title
Ratnacūḍasūtra used by Śāntideva is confirmed as referring to this text by comparison with the Kangyur recension. The
Ratnacūḍaparipṛcchāsūtra is also quoted briefly in the
Ratnagotravibhāga without mentioning it by name.
