Cause and effect

He who is realised by transcending the world of cause and effect, in deep contemplation, is expressly declared by the scriptures to be the Supreme Brahman. He is the substance, all else the shadow. He is the imperishable. the knowers of Brahman know him as the one reality behind all that seems. For this reason they are devoted to him. Absorbed in him, they attain freedom from the wheel of birth, death and rebirth.

The Lord supports this universe, which is made up of the perishable and the imperishable, the manifest and the unmanifest. The individual soul, forgetful of the Lord, attaches itself to pleasure and thus is bound. When it comes to the Lord, it is freed from all its fetters.
