Krishna does not need our service, but He kindly accepts it. When Krishna asks us to surrender unto Him, this does not mean that Krishna is lacking servants and that if we surrender He will profit. Krishna can create millions of servants by His mere desire. If we surrender to Krishna, we shall be saved. As Krishna says ‘Aham Tvam Sarva Papebhyo Moksayisyami : I shall free you from all sinful reactions’.
In the devotional service of the Lord, the only qualification required is surrender. Surrendering oneself is in one’s hand. If one likes, he can surrender immediately, without delay and that begins his spiritual life.
Srimad Bhagavatam begins with the surrender of the devotee unto the Absolute Person. The devotee is fully aware that he is one with the Absolute and at the same time he is in the eternal position of servant to the Absolute.
The living entity’s position is to be under the protection of the illusory energy or under Krishna’s personal protection. When a living entity is fully surrendered, he is under the direct protection of Krishna and Krishna gives him all intelligence by which he can advance in spiritual realization.
