Bhagavad-gītā As It Is · Text 17.23
Om Tat Sat, spiritual faith and proper intention
ॐ तत्सदिति निर्देशो ब्रह्मणस्त्रिविध: स्मृत: ।
ब्राह्मणास्तेन वेदाश्च यज्ञाश्च विहिता: पुरा ॥ २३ ॥
oṁ tat sad iti nirdeśo
brahmaṇas tri-vidhaḥ smṛtaḥ
brāhmaṇās tena vedāś ca
yajñāś ca vihitāḥ purā
From the beginning of creation, the three words oṁ tat sat were used to indicate the Supreme Absolute Truth. These three symbolic representations were used by brāhmaṇas while chanting the hymns of the Vedas and during sacrifices for the satisfaction of the Supreme.
