Srimad Bhagavatam Canto 11, Chapter 29, Text 03

SB 11.29.3

athata ananda-dugham padambujam
 hamsah srayerann aravinda-locana
sukham nu visvesvara yoga-karmabhis
 tvan-mayayami vihata na maninah
Therefore, O lotus-eyed Lord of the universe, swanlike men happily take shelter of Your lotus feet, the source of all transcendental ecstasy. But those who take pride in their accomplishments in yoga and karma fail to take shelter of You and are defeated by Your illusory energy.
Sri Uddhava emphasizes here that one can achieve spiritual perfection simply by taking shelter of the Personality of Godhead. Those who do so are called hamsah, the most discriminating human beings, since they are able to locate the actual source of spiritual happiness, the Lord’s lotus feet. The word yoga-karmabhih indicates that those who are attracted to or proud of achievements in the field of mystic yoga or ordinary material endeavor cannot appreciate the great advantage of obediently surrendering to the Supreme Personality of Godhead. Generally the yogis and fruitive workers are proud of their so-called achievements and are more attracted to their own endeavor than to the Lord Himself. By humbly taking shelter of Lord Krsna, one can advance easily and quickly on the path of Krsna consciousness and go back home, back to Godhead.
