The Devi is the Divine Shakti, the Consciousness and Power of the Divine, the Mother and Energy of the worlds. All powers are hers. Sometimes Devi-power may mean the power of the universal World-Force; but this is only one side of the Shakti.
In each part of the being the Divine manifests Himself differently. In the higher parts He manifests as Power, Love, etc. but in the physical He manifests as Harmony and Beauty. Hence the problem of the expression of physical beauty is a spiritual problem.
As for our position it is that ordinary life is Maya in this sense, not that it is an illusion, for it exists and is very real, but that it is an Ignorance, a thing founded on what is from the spiritual point of view a falsehood. So it is logical to avoid it or rather we are obliged to have some touch with it but we minimise that as much as possible except in so far as it is useful for our purpose. We have to turn life from falsehood into spiritual truth, from a life of Ignorance into a life of spiritual knowledge. But until we have succeeded in doing that for ourselves, it is better to keep apart from the life of Ignorance of the world — otherwise our little slowly growing light is likely to be submerged in the seas of darkness all around it. Even as it is, the endeavour is difficult enough, it would be tenfold more difficult if there were no isolation.
A single and infallible look comes down,
A silent touch from the supernal's air
Awakes to ignorant knowledge in its acts
The secret power in the inconscient depths,
Compelling the blinded Godhead to emerge,
Determining Necessity's rude dance
As she passes through the circuit of the hours
And vanishes from the chase of finite eyes
Down circling vistas of aeonic Time.
