Happiness is the essential nature of the soul. It is manifested after withdrawal and cessation of all activities. Having perceived that enjoyment and experience are fanciful creations of the mind, I lie down (enjoying whatever comes my way ordained by the Divine).
Having forgotten that this blissful nature is inherent in one’s self, a man is verily enmeshed into samsara which is terrible (owing to birth, death and other miseries) and yet strange (as it consists of birth in celestial, subhuman, human and other-species).
He, who (being ignorant of his innate blissful state) thinks of finding his object (happiness) elsewhere (outside his self), is like an ignorant person who, with a desire to get water (to quench his thirst), leaves water (near him, but) runs after the mirage.
