Every living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.
Unless one is happy, one cannot bestow happiness on others.
Turn the mind inward and cease thinking of yourself as the body; thereby you will come to know that the self is ever happy. Neither grief nor misery is experienced in this state.
Discover your undying Self and be immortal and happy.
