As a lamp in a windless flame does not flicker –
To such is compared
The yogin of the controlled mind,
Performing the Yoga of Self.
Houston Smith: The physical world is constantly changing; it is a scene of perpetual perishing. Sages, however, through deep introspection, came to the conclusion that whatever ceases to exist cannot be the ultimate reality. An all-pervading consciousness, which by its nature is eternal and indestructible, can alone be the ultimate reality. We catch glimpses of this all-pervading reality when we encounter people who show tremendous courage, extraordinary creativity, and boundless compassion.
