It is not about becoming so great that he is an impossible thing; the part never equals the whole, and the spiritual being always remains a tiny fragment of the Supreme Lord. Therefore, his oneness with the Lord comes from sharing the interests of the Lord.
The Lord desires that all beings think of Him constantly, become His devotees and worship Him in all circumstances. God wants to see all beings think of Him. All must offer their homage to God. This is the will of the Sovereign Lord, and it is the duty of the sage to strive to fulfill his desire. Now, as the Lord is unlimited, so too is his desire. There is therefore no interruption or limit in the service of the holy being to God.
In fact, the spiritual world sees an endless competition unfolding between the Lord and his servant. The Lord wishes to satisfy his unlimited desires, and the servant strives to serve him to fulfill his unlimited desires. It is in this sense that there is an infinite unity of interest between the Lord and his devotee.
Logos 158
The Lord says: “Leave all your illusory occupations there in this world and just surrender to Me. The consequences of your faults, I will free you from them.”
The Eternal Supreme created the material universe for the souls incarnated and conditioned by the matter and the illusory energy, who desire to dominate it and to feel the sensory benefits. This universe is not made for those who have no desire for sensory satisfaction and who remain constantly absorbed in the service of absolute love of the Lord, eternally aware of God. For them, the spiritual world continues to exist eternally, and this is where they find their joy. Those who have found refuge with the Lord, the material universe has no value because danger threatens there with every step, it is not intended for holy beings, but rather for souls eager to dominate the material energy to their own risks.
God shows such benevolence that He gives souls captivated by the pleasure of the senses a separate world, created by Him, to allow them to benefit from existence as they wish. The Lord reluctantly creates the material universe, but He descends there in His personal form or sends there one of His sons or one of His trusted servants, to instruct the conditioned souls, and He also transmits to them his directives through the holy scriptures.
All this work of preaching takes place at the same time as creation, in order to convince the misguided souls who languish in the material universe to come back and surrender themselves to Him.
