“Disturbance is due to want of an ultimate goal, and when one is certain that Krishna 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 Krishna is certainly always in distress and is without peace, however much one may make a show of peace and spiritual advancement in life.” (Shrila Prabhupada, Bhagavad-gita, 2.66 Purport)
