Savitri, Book II, The Book Of The Traveller Of The Worlds, Canto II, The Kingdom Of Subtle Matter, Part 3, Pages 111 – 115
King Aswapathy is moving through the Subtle Physical plane, the first step on the World Stair. His senses are ravished with delight and the king enjoys that fine material paradise, but its limitations can not hold him long. His destiny lay beyond this finer world, which is closest to our material existence. His spirit wants more than being’s surfaces. It turned to hidden powers and deeper states, and he looked beyond for greater light. We have some of Sri Aurobindo’s diary entries in The Record Of Yoga, showing some of his success in working with his own subtle body and keeping some of the finer substance of the subtle physical plane in his own physical body. The Record Of Yoga is full of references to the subtle physical, but it is not always obvious.
