Ratnakuta (Skt. Ratnakūṭa; Tib. དཀོན་མཆོག་བརྩེགས་པ་, könchok tsekpa, Wyl. dkon mchog brtsegs pa), or 'Heap of Jewels', is a collection of 49 independent sutras comprising one of the major sections (Toh 45-93) into which the Tibetan Canon (Kangyur) is divided. The majority of the texts are Mahayana sutras dealing with classic themes such as emptiness, compassion, wisdom, the bodhisattva's vows and path.
Many of the sutras of this collection are individually cited in the treatises of the great Indian masters and are known to have circulated as sutras in their own right; only five are still extant in Sanskrit. This collection is also present in the Chinese Tripitaka.
