Among the faculties of the mind there is none which can help us in obtaining a true knowledge of self. There is none, again, who by means of the mind alone can acquire a knowledge of the knowable Being. He who knows what self is knows what self is not. He who stands on Truth knows the Supreme Soul.
न वेदानां वेदितां कश्चिदस्ति वेद्येन वेदं न विदुर्न वेद्यम्। यो वेद वेदं स च वेद वेद्यं यो वेद वेद्यं न स वेद सत्यम्॥
