The word "nirvana" brings up many different ideas. Is it some kind of space into which we disappear? Is it some strange place where we are happy all the time, without a care for the problems of the rest of the world? In this series of talks, we will explore what nirvana really is, and practical ways of getting there, learning both the theory of nirvana, through the study of the Perfection of Wisdom Sutras and practical meditation practices. We will see that nirvana is actually a very engaged state of being, where we are in total happiness but serving the world at the same time.
