Srila Bhaktivinoda Thakura’s
Vaisnava-siddhanta-mala
Q. These truths of Sri Krsna-tattva are the religious principles of the Vaishnava-dharma. What about people who are involved with other types of religion?
A. Different religions have different instructions for the worship of either Isvara (the personal God), Paramatma (the localised Supersoul in the heart) or Brahma (His all-pervading impersonality) – but all three of these types of religions are ultimately pointing in the direction of Krsna-Tattva. After the jivas evolve upwards through their various courses of development, they eventually will attain Krsna Bhakti in the end. Even though they attain the incompleteness of their various religious paths, Sri Krsna Bhakti is still available to them. The awareness of the supreme nature of Sri Krsna-tattva is the ultimate knowledge inherent within each and every living entity.
