SB 3.29.13
Translation A pure devotee does not accept any kind of liberation — sālokya, sārṣṭi, sāmīpya, sārūpya or ekatva — even though they are offered by the Supreme Personality of Godhead.
I heard that Madhvacharyaji accepts only 4 types of mukti excluding sarsti mukti(which is translated as having same opluence as the lord). Can anyone learned in Madhva Philosophy elaborate with scriptural references?
