Ketaka Gem
The Ketaka Gem – (Tib. Norbu Ketaka, Wyl. nor bu ke ta ka), a commentary on the ninth chapter of the Bodhicharyavatara written by Mipham Rinpoche, based on the teachings of Patrul Rinpoche.
Ketaka is a gemstone that is said to be able to purify water.
Lhobpon Rechunpa said:
- From the emanation of Lokeshvara, Dza Paltrul Rinpoche, [Mipham Rinpoche] received the Wisdom Chapter of the Bodhicharyavatara in only five days. Based on this, he wrote the commentary on the Wisdom Chapter known as the She Drel Keta Ka. [1]
Mipham Rinpoche himself said:
- “When I was young, I was present when many accomplished, learned lamas gave Dharma teachings, but I only seriously studied Dza Patrul Rinpoche’s teachings on the Wisdom Chapter of the Bodhicharyavatara. Later, in dependence on the kindness of my venerable lama and Manjushri, no difficulties with study ever arose for me.”
In the ninth chapter of Nectar of Manjushri's Speech, Khenpo Kunpal's commentary on the whole Bodhicharyavatara, Khenpo Kunpal closely followed (almost verbatim) Mipham Rinpoche's Norbu Ketaka.[2]
Controversy
The commentary provoked several refutations from Gelugpa scholars, especially Pari Lobzang Rabsal and Drakkar Lobzang Palden Tendzin Nyendrak. Mipham Rinpoche wrote two lengthy responses to their objections: Clear Logic Illuminating Reality (rigs lam rab gsal de nyid snang byed) in response to Pari Lobzang Rabsal, and Response to Objections: The Light of the Sun (rgal lan nyin byed snang ba) to Drakkar Lobzang Palden Tendzin Nyendrak.
