Book excerpt: The soul of the true philosopher is in perfect harmony with his divine spirit. It is the duty of every man who is capable of an unselfish impulse to do something, however little, for the welfare of Humanity, the great Orphan. Only those of exceptional purity and unconditional love for their fellow man and every living creature, may approach the sacred Majesty of Truth and hear within the sanctuary of the heart the Voice of the Silence. Raja Yoga deals with the inner man and therefore neither encourages sham, nor requires physical postures. Hatha Yoga is triply distilled selfishness. By encouraging mental passivity, it hastens the opening of mediumistic faculties resulting in gradual loss of self-control. Inductive reasoning from the known to the unknown should be promoted and practised. True contemplation is the yearning of the human soul to ascend in spirit towards its divine parent, by studying and assimilating the divine laws that govern Universe and Man, and by applying them in everyday life. In this sublime effort the soul relies on the immutable Law of Analogy that underpins the affinity between stars and man. This is the lost thread of Ariadne, which alone can guide us through the labyrinth of matter, and lead us from the unreal to the real. Those who pray silently and intensely gain their object, while those who merely mumble some formula get no answer to their prayers.
