यदा सर्वे प्रभिद्यन्ते हृदयस्येह ग्रन्थयः ।
अथ मर्त्योऽमृतो भवत्येतावद्ध्यनुशासनम् ॥ १५॥
yadā sarve prabhidyante hṛdayasyeha granthayaḥ .
atha martyo’mṛto bhavatyetāvaddhyanuśāsanam .. 15..
When all the ties of the heart are severed here on earth, then the mortal becomes immortal. This much alone is the teaching.
Swami Vivekananda Says —
When all the crookedness of the heart disappears, when all its knots are cut asunder, then alone the mortal becomes immortal. This is the way.[Source]
