free of the thirst of becoming

He who has realized the Truth, Nirvana, is the happiest being in the world. He is free from all "complexes" and obsessions, the worries and troubles that torment others. His mental health is perfect. He does not repent the past, nor does he brood over the future. He lives fully in the present. Therefore he appreciates and enjoys things in the purest sense without self-projections. He is joyful, exultant, enjoying the pure life, his faculties pleased, free from anxiety, serene and peaceful. As he is free from selfish desire, hatred, ignorance, conceit, pride, and all such "defilements", he is pure and gentle, full of universal love, compassion, kindness, sympathy, understanding and tolerance. His service to others is of the purest, for he has no thought of self. He gains nothing, accumulates nothing, not even anything spiritual, because he is free from the illusion of self, and the "thirst" for becoming. - taken from What the buddha taught by Walpola Sri Rahula
