The Yoga-sūtra also prescribes meditation on Viṣṇu, and not meditation on the void. The so-called yogīs who meditate on something other than the Viṣṇu form simply waste their time in a vain search after some phantasmagoria. We have to be Kṛṣṇa conscious – devoted to the Personality of Godhead. This is the aim of the real yoga.
