ÅšrÄ«la ÅšrÄ«nivÄsa Ä€cÄrya has sung:

The six GosvÄmÄ«s, under the direction of ÅšrÄ«la RÅ«pa GosvÄmÄ« and ÅšrÄ«la SanÄtana GosvÄmÄ«, studied various Vedic literatures and picked up the essence of them, the devotional service of the Lord. This means that all the GosvÄmÄ«s wrote many scriptures on devotional service with the support of the Vedic literature. Devotional service is not a sentimental activity. The essence of Vedic knowledge is devotional service, as confirmed in the Bhagavad-gÄ«tÄ (15.15): vedaiÅ› ca sarvair aham eva vedyaḥ. All the Vedic literature aims at understanding Kṛṣṇa, and how to understand Kṛṣṇa through devotional service has been explained by ÅšrÄ«la RÅ«pa and SanÄtana GosvÄmÄ«s, with evidence from all Vedic literatures. They have put it so nicely that even a rascal or first-class fool can be delivered by devotional service under the guidance of the GosvÄmÄ«s.
