The inner essence is the theatre stage. The sense organs are the audience. Insight from will is the pure siddhi. Accomplishment means transformation into independence. As there, so elsewhere.
Attention is the bija.
Asana is the happiness of immersion in Shakti. One's own measure is the measure suitable for measuring, giving guidance. Imperishable knowledge means destruction of births. Pour the fourth in the three like oil diffusing in water. One should enter, immersed, by one's own consciousness.
