Gyan yoga is considered by many to be revered as the highest level of path towards moksha for human kind. Actually Raja yoga, but that is to achieve divinity, and requires life time dedication to meditation, hatha yoga and severe penance. The last one to achieve moksha thru raja yoga was Guru Yogacharya Parambhansa Yogananda. Even Vivekananda the forerunner and teacher of Raja Yoga of the modern age admits not achieving the pinnacle of Raja Yoga. Anyways, i totally agree with vishontar when you say, we should go by knowledge (gyan) and not by belief. however not compltely because not all of the human beings can indulge in finding the knowledge. there are two most common and easier path we can practice - either bhakti (faith, belief) and Karma (action). By saying, there is not difference in the amount of Moksha you can attain. All four leads to the same goal, to be in the bliss, and it is good. however, bliss cannot be achieved as long as you have desire. i suggest a book by HH the Dalai Lama - A Policy of Kindness. In one of the interviews he was asked, what is the purpose of his meditation. he said, he meditates to find the bliss (nothingness). when the mind, body and soul are embodied as one rather than separate. Another question was asked if he had been meditating for so long, if he has achieved it and when. HH said, once in 1955 and haven't since then. Amused by the answer since it was 1989, why only once. and not again. HH said, when he was meditating back then, he was only meditating and never gave a chance to his heart to desire bliss. Once he found it, he desired to see it again, and never got it. btw. i am never offended by any discussion. it is just discussion where we are all tying to find the answer for the question we don't know. so.. i am having a lot of fun. A little selfish myself because i want to find the answer... that's why i cannot be enlightened... :-)
