Ka khol ma

The Ka khol ma (wyl. bka' chems ka khol ma), is a terma reveled by Atisha at the Rasa Trul Vihara (Wyl. Ra sa 'phrul). Most of the text on Tibetan history such as the Feast for the Learned (Wyl. mkhas pa'i dga' ston) by Lodrö Gyalpo are based on it.

It seems there are three different versions of the text. This kind of confusion is not surprising for a terma, since the transmission of these texts was often given to one person only (wyl. chig rgyud) over several generations. New material were added each time and it is very difficult to find the original text.
