Kalpagamasamgraha of Aryadasa, the commentary of Vadhulasrautasutra, is another text of Vadhula tradition which is being published for the first time.

It is a very important text containing significant information of the srauta rituals practised through generations who used to follow the Vadhula tradition.

Acarya Aryadasa, most likely of thirteenth century AD, is considered to be one of the ancient commentators of the Vadhulasrautasutra. In his work, he refers to his predecessors who composed many such ritualistic texts but unfortunately most of them are not available to us till date.
