Adi-Siddha (?)
The Chaturashiti-Siddha-Pravritti begins with the legend of Luipa. This may be a reflection of the belief prevalent during the period of the narrator or the translator, that Luipa was the first siddha (adi-siddha) in terms of either time or status. The first Pada of the Charyapada was also attributed to Luipa and in its commentary in Sanskrit, Munidatta mentions him as the Adisiddhacharya. It is also an indicator of the contemporary belief. But some modern scholars like Rahul Sankrityayan claimed Saraha as adi-siddha. Luipa was definitely born after Saraha, since Luipa's teacher Savaripa was Saraha's disciple, but their lifetimes probably overlapped. Both Saraha and Luipa were originators of Samvara-tantra lineages, but it was Luipa who received the title of Guhyapati (Master of Secrets) in addition to his status of adi-siddha in the lineage that practiced the Samvara-tantra according to the method of Luipa. He received direct transmission from the Dakini Vajravarahi. If Luipa obtained his original Samvara revelation in Oddiyana, the home of several of the wisdom (mother) tantras, he probably was one of the siddhas responsible for propagating this tantra in Eastern India. But whatever the tantra's provenance, Luipa became the great exemplar of Saraha’s preachings, as confirmed in the Padas assigned to him in Charyageetikosha, and his sadhana (practice) became the inspiration and example for some of the most respected names amongst the siddhas, Kambalapa, Ghantapa, Indrabhuti, Jalandharipa, Kanhapa (Krishnacharya), Tilopa and Naropa all of whom initiated into the Chakrasamvara-tantra according to the method of Luipa. Sakya tradition maintains that, three principal Guru Sampradaya (lineages of teachers) of the practice of Chakrasamvara-tantra are of Luipa, Ghantapa and Naropa. Marpa Dopa transmitted this tantra to Tibet, where it has continued as the principal yidam sadhana (practice) of the Kagyu school till date.
