ਜਦ੍ਰ ਜਦ੍ਰ ਮਨੋ ਜਾਤੀ ॥ ਤਦ੍ਰ ਤਦ੍ਰ ਬ੍ਰਹਮ ਦ੍ਰਿਸ਼ਟਾਤੀ ॥
Wherever their mind goes; there they see Brahm.
Sant Gurbachan Singh Ji quotes a classic Vedanta proverb during his discourse of the verses by Guru Amardas within Sri Raag on page 69 of Adi Guru Granth Sahib. The surrounding verses describe the state of a Knower of Braham (ਬ੍ਰਹਮ ਬੇਤਾ)
ਸਭੁ ਆਤਮ ਰਾਮੁ ਪਛਾਣਿਆ ਗੁਰਮਤੀ ਨਿਜ ਘਰਿ ਵਾਸੁ ॥੩॥
Recognizing Ram [That which is Within Everyone] in everything, those followers of the Gurus Teachings have instilled this vision within their heart.
ਸਚੁ ਵੇਖਣੁ ਸਚੁ ਬੋਲਣਾ ਤਨੁ ਮਨੁ ਸਚਾ ਹੋਇ ॥
They only see That Truth, only speak of That Truth; for their body and mind has become That Truth.
Ang 69 Adi Guru Granth Sahib
