He that beareth himself as a friend, even though unconnected by birth of blood, is a true friend, a real refuge, and a protector. He, whose heart is unsteady, or who doth not wait upon the aged, or who is of a restless disposition cannot make friends. Success (in the attainment of objects) forsaketh the person whose heart is unsteady, or who hath no control over his mind, or who is a slave of his senses, like swans forsaking a tank whose waters have dried up.

In plain words: Someone who acts like a friend, even if not family, is a true friend and protector. People who are unsteady, restless, or do not respect elders cannot keep friends. Success leaves those who cannot control their mind and senses, like swans leaving a dried-up pond.
