Jaina layman. There is little doubt that it is one of the most popular Jaina texts and a copy or two of the work are to be found virtually in in every Digambara bhāņdāra. The only available Sanskrit commentary on it is by Prabhācandra, about whose exact date there is some doubt as we have a formidable number of Jaina scholars bearing that name. The work has been highly praised by Vădirāja in his Pārsvanāthacarita, 50 which was completed in Saka 947 corresponding to ap 1025. The commentator Prabhācandra is also full of praise for this work." Authors like Cāmundarāya and Padmaprabha have also freely used it.52
Samantabhadra was looked upon as a model by later Jaina savants, including the great Jinasena 1.53 That scholar represents him as a supreme poet, capable of destroying the dense darkness of ignorance by the lightning of his wisdom.
