Verse 125

याज्ञवल्क्येति होवाच कतिभिरयम- द्य ब्रह्मा यज्ञं दक्षिणतो देवताभिर्गोपा- यतीत्येकयेति कतमा सैकैति मन एवे- त्यनन्तं वै मनोऽनन्ता विश्वे देवा अन- न्तमेव स तेन लोकं जयति ॥ ९ ॥

In plain words

'Yājñavalkya,' he asked, 'how many deities are guarding the sacrifice for the Brahmā priest today, seated on the south side?' 'One,' came the answer. 'Which one?' 'The mind.' 'Because the mind is without limit, and the Viśvedevas are without limit — by the limitless he wins the limitless world.'
