CC Madhya-lila

When the mother Vedas [śruti] is questioned as to whom to worship, she says that You are the only Lord and worshipable object. Similarly, the corollaries of the śruti-śāstras, the smṛti-śāstras, give the same instructions, just like sisters. The Purāṇas, which are like brothers, follow in the footsteps of their mother. O enemy of the demon Mura, the conclusion is that You are the only shelter. Now I have understood this in truth.
