Adi Sankaracharya

There are two paths open to man in this world, the path that leads to fulfillment of worldly desires and the path to liberation. The first, fulfillment of desires, is the sole source of all sorrow and becomes insipid in no time. Only people lacking in discrimination take to this path. The other path leads to the attainment of Brahman, the imperishable source of infinite bliss. Wise men of discrimination resort to this path.
