Once you let your mind free, the expressions are unlimited, and then the mind becomes effulgent. The mind becomes awareness, and then the mantra becomes dynamic, the yantra becomes powerful and the mandala becomes real. You can project your thought force; you can transmit your thought waves. The mind can produce waves which can travel thousands of miles instantaneously.
With this mind, we can also enter into samadhi or the spiritual state. With this mind, we can love our children, husband, wife and neighbours. With an untrained mind, you cannot love your neighbours. This undisciplined mind cannot have compassion for other human beings. We talk about love and compassion; it is all intellectual, not real. It is all false talk. It is only a disciplined mind that has compassion and love.
