O lotus-eyed Lord, generally those yogīs who try to steady the mind experience frustration because of their inability to perfect the state of trance. Thus they weary in their attempt to bring the mind under control.
Purport
Without the shelter of the Supreme Lord, a yogī easily becomes discouraged in the difficult task of fixing his mind on the Supreme.

Translation
O lotus-eyed Lord! Generally those yogīs who try to absorb their minds in Brahman experience frustration. Because of their inability to perfect samādhi, they become fatigued in their attempt to bring the mind under control.
He explains why the process is difficult. Those who absorb the mind in Brahman (yuṣjanatah) become frustrated. Because of inability to attain samādhi, they become fatigued in controlling the mind.
