Not any specific religion or custom or tradition, and not even your lineage can pledge you a happy and successful life. If it would have been, the people who fall in some particular religion or creed or following some particular tradition would all be living in abundance of all kinds! But, unfortunately, we do not find the same. Some are very successful and happy, and others are compelled to live destitute and indigent. The religion, caste, creed, race, custom, tradition and other stratification are social concepts and creations for organizing and directing a group of people in a particular direction, which can help you to be part of the crowd but not part of the ecstasy that is the natural quest of the human on the earth.
