Happiness and misery are products of the mind and to be able to enjoy life one should cultivate and pursue right resolutions. How this can be done is explained in this book.
When we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were but we shall understand the whole thing. The same phenomena will remain but with a new meaning.
-Swami Vivekananda
