We have two main instruments: the mind and the heart. The mind finds it difficult to be happy, precisely because the mind consciously enjoys the sense of separativity. It is always judging and doubting the reality in others. This is the human mind, the ordinary physical mind, the earth-bound mind. But we also have the aspiring heart, the loving heart. This loving heart is free from insecurity, for it has already established its oneness with the rest of the world.
