Everyone is independent to think or desire, but the fulfillment of one’s desire depends on the supreme will. This law is expressed as “Man proposes, God disposes.”
Srimad Bhagavatam 3.4.11,
Vedanta is the last word in Vedic wisdom, and the author and knower of the Vedanta philosophy is Lord Krishna; and the highest Vedantist is the great soul who takes pleasure in chanting the holy name of the Lord. That is the ultimate purpose of all Vedic mysticism.
Always think of the Lotus Feet of Lord Krishna and you will find no difficulties in executing the tasks allotted to you by Krishna.
Every living entity, especially persons in the human race, must feel grateful for the benedictions offered by the grace of the Supreme Lord.
Srimad Bhagavatam 2.3.21,
Surrendering means, "Surrendering the mind to Lord Krishna by thinking only about Him and by serving Him. The natural state of the mind is to think of Krishna".
All sins are destroyed and all good fortune is created by the Supreme Lord's qualities, activities and appearances and words that describe them animate, beautify, and purify the world. On the other hand, words bereft of His glories are like the decorations on a corpse.
"You are what you eat". Our bodily constitution and mental atmosphere are determined according to how and what we eat.
