Regarding your question about annamoya, pranamoya, etc. Yes, they are different stages of consciousness. Different living beings are situated in different consciousness, Some are satisfied in the matter of eating and sleeping, they are on the annamoya stage. Pranamoya means those who can simply survive in the struggle for existence. Manomoya means philosophical speculation. Jnanamoya means self-realization, vijnanamoya means application of that stage in practical life, and when there is the right perfection of life that is anandamoya stage or Krsna Consciousness.
So by the grace of Lord Caitanya, in this age our movement is giving directly the anandamoya stage, and anyone can visit our Temple and see how our students are in blissful life. Naturally they are in jolly mood by chanting, dancing, and taking Prasadam. Your regular chanting of Mahamantra and reading of books will keep you always fit for pushing on this movement. This formula should be rigidly followed by everyone of us.
