Viṣṇu is present there. He . . . in the midst of worshiping other demigods, Viṣṇu is presented. That is the system in Vedic process. So therefore Viṣṇu is Supreme. Why Viṣṇu's sanction is required? Therefore it is understood, although in different Purāṇas different types of worship for different types of demigods are recommended, but the ultimate sanction is of Viṣṇu. Therefore Viṣṇu becomes supreme.
So from this verse, Lord Caitanya wants to impress upon us that "Don't be misguided for worshiping different demigods. The ultimate issue—the Viṣṇu is worshipable." Ārādhanānāṁ sarveṣāṁ viṣṇor ārādhanaṁ param (Padma Purāṇa).
Even in the Śiva Purāṇa it is stated that Pārvatī, the wife of Lord Śiva, he was, she was asking Lord Śiva that "Sir, worship . . . which . . . which worship is the best?" There are different kinds of worship mentioned in the Vedic literature. So Lord Śiva replied, ārādhanānāṁ sarveṣāṁ viṣṇor ārādhanaṁ param: "There are different kinds of worship, but the best and the supreme worship is worship of Viṣṇu." Then again he gives more stress:
- ārādhanānāṁ sarveṣāṁ
- viṣṇor ārādhanaṁ param
- tasmāt parataraṁ devī
- tadīyānām ārādhanam
- (Padma Purāṇa)
"And more than Viṣṇu worship is to worship the devotee of Viṣṇu." Tasmāt parataraṁ. Viṣṇu ārādhanam is the best. And better than the best worship is to worship the devotees of Viṣṇu, Vaiṣṇava. This is recommended in the Śiva Purāṇa.
