One who is fully surrendered is qualified with the six following characteristics. (1) The devotee has to accept everything that is favorable for the rendering of transcendental loving service to the Lord. (2) He must reject everything unfavorable to the Lord's service. This is also called renunciation. (3) A devotee must be firmly convinced that Krsna will give him protection. No one else can actually give one protection, and being firmly convinced of this is called faith. This kind of faith is different from the faith of an impersonalist who wants to merge into the Brahman effulgence in order to benefit by cessation of repeated birth and death. A devotee wants to remain always in the Lord's service. In this way, Krsna is merciful to His devotee and gives him all protection from the dangers found on the path of devotional service. (4) The devotee should accept Krsna as his supreme maintainer and master. He should not think that he is being protected by a demigod. He should depend only on Krsna, considering Him the only protector. The devotee must be firmly convinced that within the three worlds he has no protector or maintainer other than Krsna. (5) Self-surrender means remembering that one's activities and desires are not independent. The devotee is completely dependent on Krsna, and he acts and thinks as Krsna desires. (6) The devotee is meek and humble. As stated in Bhagavad-gita:

"I am seated in everyone's heart, and from Me come remembrance, knowledge and forgetfulness. By all the Vedas am I to be known; indeed I am the compiler of Vedanta, and I am the knower of the Vedas." (Bg. 15.15)
