The psychic or spiritual consciousness gives you the deep inner realisation, contact with the Divine, liberation from external fetters; but for this liberation to be effective, for it to have an action on the rest of the being, the mind must be open enough to be able to hold the spiritual light of Knowledge, the vital must be powerful enough to handle the forces behind appearances and dominate them, and the physical should be disciplined, organised enough to be able to express the deep experience, in the movements of each day and each moment, and live it integrally.
If one of these things is lacking, the result is not complete. One can make light of this thing or that under the pretext that it is not the most important, the central Thing—and to neglect outer things certainly cannot prevent you from entering into spiritual communion with the Supreme, but that is good only for a flight from life.
If we are to be total, complete beings, to have an integral realisation, we should be able to express our spiritual experience mentally, vitally and physically. And the more our expression is perfect, executed by a complete and perfect being, the more integral and perfect will our realisation be.
For someone who wants to follow the integral yoga nothing is useless and nothing must be neglected…. The main thing is to know how to put each thing in its place and to hand over the government to what truly has the right to govern.
