6.3.16

यं वै न गोभिर्मनसासुभिर्वा हृदा गिरा वासुभृतो विचक्षते । आत्मानमन्तर्हृदि सन्तमात्मनां चक्षुर्यथैवाकृतयस्तत: परम् ॥ १६ ॥

As the different limbs of the body cannot see the eyes, the living entities cannot see the Supreme Lord, who is situated as the Supersoul in everyone’s heart. Not by the senses, by the mind, by the life air, by thoughts within the heart, or by the vibration of words can the living entities ascertain the real situation of the Supreme Lord.
