This is a verse from the Stotra-ratna (21), composed by Alabandaru Yamunacarya. One's relationship with the Supreme Personality of Godhead may be reestablished even after one has fallen into the ocean of nescience, which is the ocean of material existence involving the repetition of birth, death, old age and disease, all arising out of the acceptance of the material body. There are 8,400,000 species of material life, but in the human body one attains a chance to get release from the repetition of birth and death. When one becomes the Lord's devotee, he is rescued from this dangerous ocean of birth and death. The Lord is always prepared to show His mercy to the fallen souls struggling against miserable material conditions. As Lord Krsna states in the Bhagavad-gita (15.7):

"The living entities in this conditioned world are My eternal fragmental parts. Due to conditioned life, they are struggling very hard with the six senses, which include the mind."
