The human intellect has not been able to conceive of anything more noble and sublime in the history of the world than the teachings of the Upanishads.
SivanandaInternalize the vagrant mind and fix it in the Lord. Then the meditation will be profound and intense. Don't open the eyes. Don't move from the seat. Melt yourself down into Him. Dive in the deep corners of your heart. Get immerse in the brilliant Atman. Drink the nectar of Immortality. Now enjoy the silence. Son of the nectar! Rejoice! Peace! Silence! Glory!
SivanandaThe impersonal aspect [of God] (Nirakara, Nirguna) is called Brahman, or 'unknowable' by Herbert Spencer, 'will' by Schopenhauer, Absolute Noumenon by some 'substance' by Spinoza. The personal aspect (Sakara) of that Being is termed 'Ishvara' or Allah, Hari, Jehova, Father in Heaven, Buddha, Siva, etc. Just as vapour or steam is formless, so also God is formless in His unmanifested or transcendental state.
