Could an individual succeed in stopping these thoughts of the manifested universe from overpowering him, he would attain to a knowledge of the Void. This can be done by yoga, and the consequent state is technically termed "the vacuum mind." Naturally there is nothing in the void to suffer the pains of illness, the decay of old age, the transition of death, and the miseries of ill-fortune. Therefore it is said that he who succeeds in attaining mentally to it, succeeds also in attaining the blessed life of exalted peace.
