A momentous feature of Indian culture is characterised by a powerful current of three affirmations. There is, first, the affirmation that the truths of the physical and supra-physical realities can be best grasped, known and possessed by us through faculties which lie above the ranges of physical senses and rational intelligence. Secondly, it is affirmed that these faculties can be developed by pursuit of assured methods resulting from the principles, powers and processes that govern the experiences and realisations of the highest possible objects of knowledge. And, finally, there is the affirmation that science, philosophy, poetry, religion and other disciplines, whatever their specific distinctions from each other and whatever their conclusions, they can reach or fulfil their goals when they open up to those higher faculties and powers and realisations achieved by the ever-progressive development of those faculties.
