This is a prakaraṇa work summarising important tenets by Kṛṣṇayajvan (18th Cent.) on the Pūrva Mīmāṃsā school of philosophy. It is an essential text for anyone studying Indian logic and the rules of Vedic interpretation. It clarifies the three types of Vedic injunctions (vidhi) including; Apūrva-vidhi, Niyama-vidhi, Parisaṅkhyā-vidhi. The text contains only first Apūrva-vidhi. It is written in Devanagari script and Sanskrit language but it starts with folio no. 4 and holds only 22 folio so it seems it is an incomplete manuscript. on the last cover of the manuscript has written 'उमानाथस्येदं पुस्तकं' so it seems that he is the owner of this text.
