The science of yoga has not brought any great surprise to the world, but it has given man the hope of awakening the potential that is dormant in every individual. When man was engrossed in ignorance, he was only thinking and identifying with the material part of his existence – the body, mind and emotions. He was then caught in the realm of pain and pleasure. But it seems that the universal consciousness is taking a round about turn and man is gradually becoming more concerned with the discovery of his real nature, and the means by which he can achieve this goal.
In order to purify the mind, it is necessary for the body as a whole to undergo a process of absolute purification. Hatha yoga is also known as the science of purification, not just one type of purification but six types. The body has to be cleaned in six different ways for six different impurities. When we clear the body of these impurities, the nadis function and the energy blocks are released. Then the energy moves like wave frequencies throughout the channels within the physical structure, moving right up to the brain.
The main objective of Hatha Yoga is to create an absolute balance of the interacting activities and processes of the physical body, mind and energy. When this balance is created, the impulse generated give a call of awakening to the central force which is responsible for the evolution of human consciousness. Although yoga has proved to be very effective in the treatment of many impossible and incurable diseases, the therapeutic effect of yoga is only a byproduct and incidental.
Hatha yoga is not only a method of preparing the system for spiritual awakening, it is also a very important science of health. Since ancient times it has been used by yogis and rishis for the relief and elimination of all kinds of diseases, disorders and defects. It is true that the practices require a bit more time and effort on the part of the patient than the conventional therapies. Rut in terms of permanent, positive results, as well as the saving of enormous expenditure on medicines, they are certainly well worth it.
