The Great Epic of the Bhārata dynasty 6.24.39

6.24.39

eṣā te'bhihitā sāṃkhye buddhiryoge tvimāṃ śṛṇu |
buddhyā yukto yayā pārtha karmabandhaṃ prahāsyasi || 39 ||

What grief then is there in this? One looks upon it as a marvel; another speaks of it as a marvel. Yet even after having heard of it, no one apprehends it truly. The Embodied (soul), O Bharata, is ever indestructible in everyone's body. Therefore, it behoveth thee not to grieve for all (those) creatures. Casting thy eyes on the (prescribed) duties of thy order, it behoveth thee not to waver, for there is nothing else that is better for a Kshatriya than a battle fought fairly. Arrived of itself and (like unto) an open gate of heaven, happy are those Kshatriyas, O Partha, that obtain such a fight. But if thou dost not fight such a just battle, thou shalt then incur sin by abandoning the duties of thy order and thy fame. People will then proclaim thy eternal infamy, and to one that is held in respect, infamy is greater (as an evil) than death itself. All great car-warriors will regard thee as abstaining from battle from fear, and thou wilt be thought lightly by those that had (hitherto) esteemed thee highly. Thy enemies, decrying thy prowess, will say many words which should not be said. What can be more painful than that? Slain, thou wilt attain to heaven; or victorious, thou wilt enjoy the Earth. Therefore, arise, O son of Kunti, resolved for battle. Regarding pleasure and pain, gain and loss, victory and defeat, as equal, do battle for battle's sake and sin will not be thine. This knowledge, that hath been communicated to thee is (taught) in the Sankhya (system).

Listen now to that (inculcated) in Yoga (system). Possessed of that knowledge, thou, O Partha, wilt cast off the bonds of action. In this (the Yoga system) there is no waste of even the first attempt. There are no impediments. Even a little of this (form of) piety delivers from great fear. Here in this path, O son of Kuru, there is only one state of mind, consisting in firm devotion (to one object, viz., securing emancipation). The minds of those, however, that are not firmly devoted (to this), are many-branched (un-settled) and attached to endless pursuits. That flowery talk which, they that are ignorant, they that delight in the words of the Vedas, they, O Partha, that say that there is nothing else, they whose minds are attached to worldly pleasures, they that regard (a) heaven (of pleasures and enjoyments) as the highest object of acquisition,--utter and promises birth as the fruit of action and concerns itself with multifarious rites of specific characters for the attainment of pleasures and power,--delude their hearts and the minds of these men who are attached to pleasures and power cannot be directed to contemplation (of the divine being) regarding it as the sole means of emancipation. The Vedas are concerned with three qualities, (viz., religion, profit, and pleasure).
