Contents of the Gita Summarized
Chapter 2: Verse-65
For one thus satisfied [in krsna consciousness], the threefold miseries of material existence exist no longer; in such satisfied consciousness, one’s intelligence is soon well established.
Chapter 2: Verse-66
nästi buddhir ayuktasya
One who is not connected with the Supreme [in krsna consciousness] can have neither transcendental intelligence nor a steady mind, without which there is no possibility of peace. And how can there be any happiness without peace?
Unless one is in krsna consciousness, there is no possibility of peace. So it is confirmed in the Fifth Chapter  that when one understands that krsna is the only enjoyer of all the good results of sacrifice and penance, that He is the proprietor of all universal manifestations, and that He is the real friend of all living entities, then only can one have real peace. Therefore, if one is not in krsna consciousness, there cannot be a final goal for the mind. Disturbance is due to want of an ultimate goal, and when one is certain that krsna is the enjoyer, proprietor and friend of everyone and everything, then one can, with a steady mind, bring about peace. Therefore, one who is engaged without a relationship with krsna is certainly always in distress and is without peace, however much he may make a show of peace and spiritual advancement in life.krsna consciousness is a self-manifested peaceful condition which can be achieved only in relationship with Krsna.
