The story of Buddha and its inner meaning and significance. Distinction between true renunciation, vairagya impelled by a positive seeking, and a temporary state of disillusionment which is essentially a negative state without much force in it. The need for balance and moderation on the path of yoga. Tamas, rajas and sattwa, and necessity of first bringing the tamoguna and rajoguna under the control of Sattwa to achieve the mastery of nature.
