This Atman is Satchidananda (Existence-Absolute, Consciousness-Absolute, Bliss-Absolute). It exists in the past, present and future. So it is Sat. It is pure or Absolute Consciousness without any thought. So it is Chit. It is absolute Bliss. So it is Ananda.
Swami Sivananda lived 1887-1963. His teachings are as much inspiring today as they were half a century ago. A life in accordance to his inspiration can lead you to joy, love and highest realisation. Quotes from Amrita Gita copyright The Divine Life Society
