Bhagavad Gita 4.2
एवं परम्पराप्राप्तमिमं राजर्षयो विदुः। स कालेनेह महता योगो नष्टः परन्तप॥
evaṁ paramparā-prāptam imaṁ rājarṣhayo viduḥ sa kāleneha mahatā yogo naṣhṭaḥ parantapa
Translation
This, handed on down the line, the King-Sages knew. This yoga by great efflux of time decayed in the world, O Parantapa.
What it means
Handed down through the royal sages, this yoga decayed over long time as its custodians weakened. Even the highest knowledge erodes when the vessel is unfit; every generation must re-receive it.
Try this today
Teachings decay in transmission. What survives as ritual may have lost the living method.
Something to reflect on
What practice do I perform whose purpose I have never questioned?
