In this continuation volume the author makes an indepth study of the causes for worries and anxieties and brings out the saving power of love. He also discusses border-line topics like life after death. At every stages he cites examples from the lives of persons who have been able to attain success, physically, mentally and spiritually.
Those who have succeeded in attaching or detaching their minds at will have succeeded in Pratyahara, which means gathering towards, checking the outgoing powers of the mind, freeing it from the thralldom of the senses. When we can do this, we shall really possess character; then alone we shall have taken a long step towards freedom. Before that, we are mere machines.
-Swami Vivekananda
