There is nothing more precious than our life. Because we have a precious human life, we have the opportunity to experience both temporary and ultimate happiness. We usually regard material possessions as very important and put much effort into acquiring them, but in reality our human life is our most important possession. If we lose our life, we shall have no opportunity to enjoy a human life, to practice Buddha’s teachings and to actualise our potential for enlightenment. Therefore in order to complete our spiritual journey to temporary and ultimate happiness we need to increase our lifespan, merit and our wisdom. The principal method for doing this is the Yoga of Amitayus.
