"knowledge is the boat you can use to cross the river of sins and impurity but you will have to leave that boat on the bank of the river and explore this world practically". I was searching for the book to get ultimate happiness and I found this book by the holy Dalai lama. This book has the potential to make you very kind, compassionate and end your hunger for infinite desires and lust to lead a happy (happiest) life. This book is recommended to everyone seeking pure joy in their lives.
