Your explanation of Annamoya is all right. Pranamoya means there are different types of airs, and the spirit soul is floating on the air, just like all the planets are floating in the air. This Pranamoya air is transferred by breathing exercises, but we have nothing to do with such exercises. Our prana, or life, is surrendered to Krishna. That is the first class yoga system approved by Lord Krishna in the Bhagavad-gita. This Pranamoya, Annamoya, etc. are different stages for persons who are too much engrossed in the bodily concept of life. Our philosophy begins from the point where we immediately accept that I am not this body; I am pure spirit soul, servant of God, Krishna. Therefore, these studies are meant for neophyte transcendentalists. But this devotional service is far above such platform. Regarding your last question, generally those who are attracted very much to Lord Caitanya and Goswamis are understood to develop to the conjugal love stage with Lord Krishna. So I am very much pleased, and I congratulate you.
I have given you the spiritual names as follows:Sriballavah Das Brahmacari (Vin Fiocco). Sriballavah is another name for Narayana.Pranaballavah Das Brahmacari (Bruce Webster). Pranaballavah means Krishna. Vallabha means beloved and prana means life.Kamalavati Dasi (Elicia Heller). Kamalavati means the goddess of fortune.
This life is very flickering. At any moment you may die so we must cling very close to the instruction of higher authorities, the spiritual master and Lord Krishna in Bhagavad-gita. So I think that you can follow the instructions. You are intelligent hard working boy. In the meantime until you get stronger, you should remain in the association of devotees. In this way you will get a taste for spiritual life. In Bhagavad gita it is stated: :mac-citta mad-gata-prana/ bodhayantah parasparam/ kathayantas ca mam nityam/ tusyanti ca ramanti ca (BG 10.9).
