It is to serve Krishna, God, the Supreme Person that we have been created; this is the primary reason for our existence.
The celestial beings, including the fathers of mankind, and those to whom the Lord has entrusted the management of the various sectors of the galaxy, were created to serve Krishna, God, the Supreme Person, and to carry out His orders.
We are all eternal servants of Krishna, created for His pleasure.
The holy beings, devotees of Krishna, think differently from the human mass. It is misleading to judge a devotee by his behavior. He seems to act like all people, but it does not matter what he does, for he does it only for Krishna's pleasure.
The Supreme Lord, Krishna, the Sovereign Divine Person, is by nature overflowing with joy, and He multiplies Himself to increase His spiritual and absolute happiness. And we the separate beings already exist as minute parts of the Supreme Lord for the satisfaction of His divine senses.
The living being, the soul incarnated in a human, animal or vegetable body, belongs to the internal energy of the Lord and is therefore also identical to Him, but it never equals and surpasses God, Krishna. God and other beings all possess their own individuality. Spiritual beings distinct from God can also, with the help of material energy, exercise a certain creative power, but none of their creations equal and surpass those of the Lord.
It is only the unreasonable, insane minds that claim to be One with God, and thus are led astray by the illusory energy that plunges them into the darkness of ignorance. In their misguidance they have no other recourse than to recognize the supremacy of Lord Krishna, and to voluntarily engage in His service of love and devotion, for it is to do so that they have been created. If they do not return to this original and natural duty, the world can know neither peace nor tranquility.
The spiritual being is but a tiny fragment of Krishna, created by the Lord to contribute to His joy. Just as an organ contributes to the harmonious functioning of the whole body, but cannot enjoy by itself in an autonomous way, the only role of the being distinct from God is to be united with the Lord in a spirit of “cooperation”.
The hands in bringing food to the mouth, the feet in moving the body, the teeth in chewing the food, the eyes in observing…, all act to satisfy the stomach, the “energy centre” on which the whole organism depends. No part of the body can relate the enjoyment of its actions to itself. We feed the tree by watering its roots, not its branches, and the body by feeding the stomach. Another example, the red blood cells have the task of transporting oxygen from the lungs to the tissues, and in return they collect carbon dioxide, in order to evacuate it when exhaling. As for the white blood cells, their role is to defend the body against external aggression. This relationship also exists between the Lord, the supreme creator and beneficiary of all that is, and the spiritual beings, his subordinate creatures. As parts of the Whole that is God, the Supreme Person, we must all contribute to His joy, to His satisfaction. Only in this way will we find our own happiness.
This is our eternal duty, to make Krishna happy, to please Him, and simultaneously the Lord will immerse us in unimaginable happiness for eternity.
