श्री दत्तात्रेय हृदयराजः

A second and quite separate text called the heart of Dattātreya, which shares almost nothing with the first beyond the name and the seed-syllables. Its viniyoga names Kālākarṣaṇa as the seer and jagatī as the metre, where the other names Īśvara and anuṣṭubh. The body of it is thirteen verses that each close on the same line — the one whose form is the three gods, lord Dattātreya, to the guru salutation — and each fills its four lines with names drawn deliberately from all three: Viśveśvara and Nīlakaṇṭha beside Hari and Vāsudeva, Gaṅgādhara beside Śrīpati, the ash and the skin garment beside the yellow silk. Its closing verses set out a regimen rather than a promise, prescribing the twenty-four verses told twelve times over and a preliminary observance counted by the number of the sun, after which the reciter is said to obtain sight of him.
