The Force which has to be called down from above must be pure and quiet because there are all kinds of forces - it will not do to call them all. And one must have sincerity.
There is the physical mind which is mechanical but the awareness which is the essential character (dharma) of the mind is also to some extent present there.
The yoga we practice is not for ourselves alone, but for the Divine; its aim is to work out the will of the Divine in the world, to effect a spiritual transformation and to bring down a divine nature and a divine life into the mental, vital and physical nature and life of humanity. Its object is not personal Mukti, although Mukti is a necessary condition of the yoga, but the liberation and transformation of the human being. It is not personal Ananda, but the bringing down of the divine Ananda - Christ's kingdom of heaven, our Satyayuga - upon the earth.
Spirituality is the master key of the Indian mind. It is this dominant inclination of India which gives character to all the expressions of her culture. In fact, they have grown out of her inborn spiritual tendency of which her religion is a natural out flowering. The Indian mind has always realized that the Supreme is the Infinite and perceived that to the soul in Nature the Infinite must always present itself in an infinite variety of aspects.
