The Hidden Teaching Beyond Yoga gave the impression that the spiritual had been set aside and a mental plane adopted; but, as the opening chapters explained, this was done deliberately in order to interest a large body of intellectual people in the West who did not accept mysticism but who might be led gradually into it if the approach were made through the reasoning faculty and they were thus convinced. This book started from their standpoint and the second volume tried to lead them right into the spiritual camp. It is not enough merely to preach to the converted. The simple spiritual teaching will help a certain number of people and no more. Owing to the advance of science there are lots of people with intellectually tangled minds who also need help.
