Lord Caitanya instructed the mass of people in the sankhya philosophy of acintya-bhedabheda-tattva, which maintains that the Supreme Lord is simultaneously
one with and different from His creation. Lord Caitanya taught this philosophy through the chanting of the holy name of the Lord. He taught that the holy name of the Lord is the sound incarnation of
the Lord and that since he Lord is the absolute whole, there is no difference between His holy name and His transcendental form.
Thus by chanting the h oly name of the Lord one can directly associate with the Supreme Lord by sound vibration. As one practices this sound vibration, he passes through three stages of development:
the offensive stage, the clearing stage and the transcendental stage.
In the offensive stage one may desire all kinds of material happiness, but in the second stage one becomes clear of all material contamination. When one is situated on the transcendental stage, he attains the most coveted position - the stage of loving God. Lord Caitanya taught that this is the highest stage of perfection for human beings.
