<p class="p1">Therefore get up and prepare to fight. After conquering your enemies you will enjoy a flourishing kingdom. They are already put to death by My arrangement, and you, 0 Savyasacin, can be but an instrument in the fight.</p> <p class="p1">(Bhagavad Gita 11.33)</p> <p class="p1"> </p> <p class="p1">Are we just an instrument with everything pre-decided as mentioned above ?</p> <p class="p1">If Yes, then why is Krishna giving any instruction to Arjuna at all ?</p> <p class="p1">How much freedom do we actually have?</p> <p class="p1">How to increase our free will ?</p> <p class="p1">How to change our destiny ?</p>
