BOW AND ARROW
The Vedic mantra pranava is the bow, the pure living entity himself is the arrow, and the target is the Supreme Being. ...
The living entity tries to be happy within this material world, not understanding the target of his life. When he is purified, however, he gives up his bodily conception of life and his false identity as belonging to a certain community, a certain nation, a certain society, a certain family and so on (sarvopadhi-vinirmuktam tat-paratvena nirmalam [Cc. Madhya 19.170]). Then he takes the arrow of his purified life, and with the help of the bow -- the transcendental chanting of pranava, or the Hare Krishna mantra -- he throws himself toward the Supreme Personality of Godhead.
If with the arrow of chanting the holy name of the Lord one pierces Lord Vishnu's lotus feet, by dint of performing this heroic activity of devotional service one receives the benefit of returning home, back to Godhead.
