To have a developed intellect is always helpful if one can enlighten it from above and turn it to a divine use.
The language of the Veda itself is sruti, a rhythm not composed by the intellect but heard, a divine Word that same vibrating out of the Infinite to the inner audience of the man who had previously made himself fit for the impersonal knowledge.
Religions, creeds and forms are only a characteristic outward sign of the spiritual impulsion and religion itself is the intensive action by which it tries to find its inward force. Its expansive movement comes in the thought which it throws out on life, the ideals which open up new horizons and which the intellect accepts and life labours to assimilate.
