Lawapa
Lawapa or Lavapa (Wylie: la ba pa; grub chen la ba pa; wa ba pa
) was a figure in Tibetan Buddhism who flourished in the 10th century. He was also known as Kambala and Kambalapada (Sanskrit: Kaṃbalapāda). Lawapa, was a mahasiddha, or accomplished yogi, who travelled to Tsari. Lawapa was a progenitor of the Dream Yoga sādhanā and it was from Lawapa that the mahasiddha Tilopa received the Dream Yoga practice lineage.
Bhattacharya, while discussing ancient Bengali literature, proffers that Lawapa composed the Kambalagītika (Wylie: la ba pa'i glu
"Lawapa's Song") and a few songs of realization in the Charyapada.
