“ ‘There are many types of Vedic literatures and supplementary Purāṇas. In each of them there are particular demigods who are spoken of as the chief demigods. This is just to create an illusion for moving and nonmoving living entities. Let them perpetually engage in such imaginations. However, when one analytically studies all these Vedic literatures collectively, he comes to the conclusion that Lord Viṣṇu is the one and only Supreme Personality of Godhead.’
Purport
This is a verse from the Padma Purāṇa.
