The aim and practice of Yoga: A radical difference in the real aim of Yoga
On account of the fact that there is a radical difference in the concept of Yoga, as presented in this volume, with corroboration from ancient canonical texts and standard books on the subject, and the generally accepted ideas, current today, it is necessary to make this distinction clear at the outset in order to avoid confusion.
According to my view all systems of Yoga embody divergent methods for the metamorphosis of consciousness.
The real aim of Yoga is not to cause an obstruction in the normal flow of thought by sustained efforts of concentration, but to open new areas of perception in the brain capable of manifesting a transhuman state of consciousness. The ideas expressed by some modern writers that the practice of concentration, carried to the required degree, can enable the Sadhaka to keep out both the sensory impressions, coming from outside, and the subconscious impulses, invading the mind from within, and in this state of freedom to experience the transcendent, do not at all present a correct picture of the processes released by Yoga or of the ultimate state to which it leads.
