In this work the numbering is of two types: natural sequence of the verses, and added ones, for enumerating the sequence supplied by the commentary. The previous type has two dots on the head and the latter type does not. [Note: It seems that now double lines mark the verses and brackets mark the aṅgas.] In the phrase kṛṣṇa-dīkṣādi-sikṣaṇam the word ādi has the sense of “in the beginning.” Thus the phrase means “acquiring knowledge after or accompanied by initiation with Kṛṣṇa mantra.” Sadhu-vartmānuvartanam (following the path of the ācāryas) means following the rules of the śruti and other scriptures enjoined by the ācāryas.
