People will ask, “Which energy do you have in mind when you speak of the heart?” Of course, it is the very same Aum, the psychic energy of the three worlds. By studying this energy, you can ascertain that its deposits are multicolored. Certainly, the deposits may be red, purple, or blue, but as they approach the heart, they lose their coloring. The crystal of the heart is white, colorless. Naturally, this resonance of the heart is not observed very often, but you should strive toward it. The ancients used to advise people to place their hands on the needles of young cedars, so that the condensed prana might penetrate their fingertips. There are many ways to receive psychic energy from the vegetable kingdom, but the one regarded as the best is an open heart that knows the line along which to strive. (Heart (opens in new tab), 14)
