Way to Immortality: Renounce Desires
यदा सर्वे प्रमुच्यन्ते कामा येऽस्य हृदि श्रिताः ।
अथ मर्त्योऽमृतो भवत्यत्र ब्रह्म समश्नुते ॥ १४॥
yadā sarve pramucyante kāmā ye’sya hṛdi śritāḥ .
atha martyo’mṛto bhavatyatra brahma samaśnute .. 14..
When all the desires that dwell in the heart fall away, then the mortal becomes immortal and here attains Brahman.
Swami Vivekananda Says —
When all the desires that trouble the heart cease, then the mortal becomes immortal, and here one attains Brahman.[Source]
