A large component of the secret of learning to rely less and less on material substance and food, and to begin more and more to assimilate prana and invisible life force, is the cultivation of LOVE. I am not sure yet if prana and Divine Love are identical or simply so closely aligned that the cultivation of love attracts prana into one's field.

The sense I get is that if you consciously cultivate a massive amount of love and compassion, and you are striving toward a breatharian mode of living, you won't need to practice sungazing or a lot of intense breathing techniques to reach your goal.
