Srila Prabhupada Lecture on Srimad-Bhagavatam, 02-25-76, Mayapur
"Thus Krsna should not be thought of as being alone but should be considered as eternally existing with all His manifestations, as described by Ramanujacarya. In the Visistadvaita philosophy, God's energies, expansions and incarnations are considered to be oneness in diversity. In other words, God is not separate from all of these; everything together is God."
Caitanya-caritamrta, Adi lila Introduction
"The Lord is the reservoir of all cosmic manifestation, animate and inanimate. The advocates of Visistadvaita-vada philosophy explain the Vedanta-sutra by saying that although the living entity has two kinds of bodies--subtle (consisting of mind, intelligence and false ego) and gross (consisting of the five basic elements)--and although he thus lives in three bodily dimensions (gross, subtle and spiritual), he is nevertheless a spiritual soul."
Caitanya-caritamrta, Adi lila 2:37
"Thus although the energies of the Supreme Personality of Godhead interact within the cosmic manifestation, each keeps its separate individual existence. Merging in the material or spiritual energies, therefore, does not involve loss of individuality. According to Sri Ramanujapada's theory of Visistadvaita, although all the energies of the Lord are one, each keeps its individuality (vaisistya)."
Caitanya-caritamrta, Adi lila 7:121
"...We Gaudiya Vaisnava follow Srila Ramanuja's philosophy almost in the same manner. Sri Caitanya Mahaprabhu gives the identification of jiva soul as the eternal servant of Krishna and is situated as marginal potency of the Lord based on the philosophy of acintya-bheda bheda-tattva. This is almost similar to Visistadvaita vada. Vaisnava philosophy is now being pushed on all over the world under the Hare Krishna movement, and we feel Sripada Ramanuja a great support for the Vaisnava philosophical understanding. It is like a combination of nyaya sruti and smrti prasthans. The Bhagavad-gita supports the Vedanta Sutra brahma-sutra-padais caiva. hetumadbhir viniscitaih. (BG. 13:5.)
"So far I am personally concerned, following the footsteps of my guru maharaj Srila Bhaktisiddhanta Sarasvati Thakura Prabhupada, we accept the principles of all the acaryas, although officially we belong to the Madhva sampradaya. Our sampradaya is known as the Madhva Gaudiya sampradaya. We find great shelter at the lotus feet of Sri Ramanujacarya because his lotus feet are the strongest fort to combat the mayavadi philosophy."
