"To summarise what has been indicated above, our aim should be complete deliverance from suffering, or stated positively, the unconditioned and perfect happiness of Nibbāna; to be differentiated from other forms of happiness which are imperfect because ‘conditioned’ by impermanence, and thus liable to revert to suffering when circumstances or ‘the conditions’ change. By an understanding of the Four Noble Truths of Buddhism we are set in the right direction to achieve this aim. But to reach this understanding the mind must be carefully prepared by moral discipline and other virtues, released from the grip of worldly pleasures and emotions and reach a state of clarity and purity through meditation and wise discrimination. Then by reflection on the three characteristics of existence, the impermanence, suffering and absence of an underlying entity, this understanding will arise giving assurance and confidence. The practical nature of the Buddha’s teaching is that it leads one gradually step by step, like a building raised brick by brick upon secure foundations." —John D. Ireland
