When the clouds are dispersed, the sun shines by itself. The whole difficulty lies in the process, in the struggle to know the real technique of the procedure and not in the actual attainment. There is struggle until the place of the switch is found, but the moment it is found, there is a sudden press of the switch with the effect of instantaneous light. Sadhana is the cessation of wandering, the return from the aberration, in order to rest in one’s native home. This requires great viveka and vichara shakti, true renunciation and persistent practice.
