CC Adi 7.97, Translation and Purport

“Compared to the ocean of transcendental bliss that one tastes by chanting the Hare Kṛṣṇa mantra, the pleasure derived from impersonal Brahman realization [brahmānanda] is like the shallow water in a canal.

In the Bhakti-rasāmṛta-sindhu (1.1.38) it is stated:

brahmānando bhaved eṣa cet parārdha-guṇī-kṛtaḥ

naiti bhakti-sukhāmbhodheḥ paramāṇu-tulām api

“If brahmānanda, the transcendental bliss derived from understanding impersonal Brahman, were multiplied a million times, such a quantity of brahmānanda could not compare with even an atomic portion of the pleasure relished in pure devotional service.”
