This mysterious human body, the temple of God, the nine gated city of Brahman, is a marvellous palace for the immortal indweller, or soul. The body is a product of the prarabdha karma (the karma that determines this present life for this individual soul). It belongs to the jiva (individual soul) and the virat (the physical world) also. The sum total of all physical bodies is virat purusha (the deity presiding over the universe).
The body is the most marvellous and delicate machine in the world. It is a highly complex mechanism. Even the most eminent doctors in the world have not yet completely understood its structure and working. One virulent microbe can destroy it in an instant. The body is surrounded on all sides by enemies and yet man lives. This is a very great mystery. This is due to the grace of the Lord. The force of prarabdha protects and nourishes it.
A spermatozoan, which is a millionth part of a drop, and an ovum, joined together, give rise to the formation of this body. What a great mystery. That subtle essence, which is the source for this, that which sustains these, is thy own self. That is truth. That is soul. Thou art That.
Realise this and free yourself from the cage of bone and flesh. The growth of the body, with all its limbs, organs, etc., from this tiny speck of sperm, proclaims the omnipotence of the Lord.
God is that wonderful architect who has built this wonderful body palace. The architect of this marvellous body has shown the greatest skill. He is the architect of all architects. The arches of buildings are nothing when compared to the arches of the body, which are a few fragile bones, joined together to form the arch of the foot, which supports the weight of the body. One tiny nerve moves the muscles of the face. The face then expresses the emotions of the mind what a grand marvel! Look at that delicate organ of the eye. One small aperture which allows a mountain to enter! This greatest architect is the Lord who dwells in the chamber of your heart. Glory to him. Prostrations to this great architect.
