The Lion's Roar: A Commentary on Sugatagarbha
By Jamgön Mipham Rinpoche
Prologue
1st teaching, 16-Dec-2008: How is buddha nature taught in sutra, tantra and Dzogchen?
Introduction
2nd teaching, 17-Dec-2008: Our teacher the Buddha has taught on buddha nature emphasizing sugatagarbha's essence (Wyl. ngo bo) by teaching on emptiness. On other occasions, he gave clarifications on its nature (Wyl. rang bzhin) by explaining its primordially present qualities. It is crucial to understand that those two aspects are in union. See Tibetan: Mipham gsung 'bum, Vol 4., p. 564-565. English: Duckworth, p.147-148
3rd teaching, 18-Dec-2008: Accuracy of scriptures can be examined by the three types of investigation and understanding establishes irreversible trust by means of the three types of valid cognition.[1] How can buddha nature (tathagatagarbha) be established in this way, as being empty in essence while cognizant in nature? See Tibetan: Mipham gsung 'bum, Vol 4., p. 566-567. English: Duckworth, p.148-149
1. Proof of the Presence of the Tathagatagarbha in all Sentient Beings
The Uttaratantra Shastra says:
1.1 The Mistaken Apprehension of Others
4th teaching, 19-Dec-2008: A refutation of the position of early Tibetan commentators concerning the interpretation of the meaning of the Uttaratantra Shastra verse. Neither is the fact that the dharmakaya pervades everything sufficient for the existent of the nature (Tib. rigs) nor can suchness be simply understood as mere emptiness in the sense of the approximate ultimate.
See Tibetan: Mipham gsung 'bum, Vol 4., p. 567-569. English: Duckworth, p.149-151
Nature (rigs) as the union of the two truths
5th teaching, 20-Dec-2008: The sugatagarbha is the indivisible union, beyond any possibility of being united or separated, of the primordial purity of the cause and effect of samsara, and untainted appearances which are natural and spontaneous clear light.

- (Wyl. tshad ma gsum) Another expression for the three types of investigation.
- The alternative translation for potential (Tib. rig; Wyl. rigs) used during the teachings is nature or the Sanskrit gotra (here go comes from guna, quality. Tra means to protect. So gotra means to protect the qualities (Wyl. yon ten skyob pa) [RY])
