5.40.29

sā tu buddhiḥ kṛtāpyevaṃ pāṇḍavānprati me sadā |
duryodhanaṃ samāsādya punarviparivartate || 29 ||

"Dhritarashtra said, It is even so as thou always teachest me. O amiable one, my heart also inclineth that very way of which thou tellest me. Although, however, I incline in my mind towards the Pandavas even as thou teachest me to do, yet as soon as I come in contact with Duryodhana it turneth off in a different way. No creature is able to avert fate. Indeed, Destiny, I think, is certain to take its course; individual exertion is futile.'"
