भवतीत्यर्थः ।यः पूर्णस्वरूपः, तं परमात्मानं योगिन एव पश्यन्ति ॥
In plain words
"Becomes" — that is the sense of it. The one whose very nature is fullness, that Supreme Self: the yogis, and only they, see him.
Close to the Sanskrit
"Becomes" — such is the meaning. He who is of the nature of fullness, him, the Supreme Self, the yogins alone see.
