Jayapataka Swami: Why did Lord Caitanya establish the acintya beda abeda tattva? That is the most complete philosophy and that unifies all the other philosophies of the Vedanta like Advaita, Vishishtadvaita, Dvaitadvaita, etc. So Lord Caitanya’s acintya beda abeda tattva unifies all the other philosophies. In the Padma Purana, it particularly says that unless one receives the mantra from these four Vaisnava Samparadayas – Sri, Rudra, Kumara, Brahma – the mantra will not be useful, not be fruitful, it will be fruitless! So Lord Caitanya by His establishing the acintya beda abeda tattva, He could combine all the other philosophies. Hare Krsna!
