The vedic culture is a very scientific and precise science, science of entire creation and the science of being as a microcosm of the macrocosm which is the physically manifested creation. It very clearly lays down the path and also how to walk on it and have the secrets of creation revealed to you so that the final merger happens with full consciousness in a disease-free body…at will. 

The reason why there are so many seekers and very few who achieve success is simple. Those who achieve success have three things in common – a Guru who has the traits of five yamas of ashtang yog, priority to the subject over other things in life and, regular practice along with service and charity.  The above three things are tied into the framework of four ashrams – brahmcharya, grihasta, vaanprasth and sanyaas. Each of these ashrams naturally flows into the next, it is not forced, the right practice of yog under a guru ensures this.
