The six Gosvāmīs of Vṛndāvana excavated this extraordinary esoteric essence of the Vedas and described the workings of the internal potency of the Lord. Before the advent of Lord Caitanya, subjects of this nature had never been discussed in such detail by any spiritual authority. Śrīla Rūpa Gosvāmī, in his play Vidagdha-mādhava, glorifies Lord Caitanya's unique contribution to mankind:
- anarpita-carīṁ cirāt karuṇayāvatīrṇaḥ kalau
- samarpayitum unnatojjvala-rasāṁ sva-bhakti-śrīyam
- hariḥ puraṭa-sundara-dyuti-kadamba-sandīpitaḥ
- sadā hṛdaya-kandare sphuratu vaḥ śacī-nandanaḥ
May that Lord who is known as the son of Śrīmatī Śacīdevī be transcendentally situated in the innermost core of your heart. Resplendent with the radiance of molten gold, He has descended in the Age of Kali by His causeless mercy to bestow what no incarnation has ever offered before: the most elevated mellow of devotional service, the mellow of conjugal love.
