Happiness is of two sorts, viz., physical and mental. The visible and invisible fruits of action, both this and the other world, are described for the sake of happiness. There is nothing more important than happiness among the fruits of the threefold objects of life. Happiness is desirable. It is an attribute of the Soul. Both virtue and Profit are sought for it. Virtue is its origin. This, indeed is its origin. The end of all acts is the attainment of happiness.
तत् खलु द्विविधं सुखमुच्यते शारीरं मानसं च। इह खल्वमुष्मिश्च लोके वस्तुप्रवृत्तयः सुखार्थमभिधीयन्ते। न ह्यतः परं त्रिवर्गफलं विशिष्टतरमस्ति स एव काम्यो गुणविशेषो धर्मार्थगुणारम्भस्तद्धेतुरस्योत्पत्ति: सुखप्रयोजनार्थ आरम्भः॥
