Baladeva is just next to Krsna in the category of object of worship. In the Maha-Vaikuntha He is manifest as, Vasudeva, Sankarsana, Pradyumna and Aniruddha. The topics of the fourth dimension lie beyond the threefold specification of the Linear, superficial and cubical magnitudes of this world.
The topics of the 5th dimension are still higher. They are words spoken by the flute of Krishna
