Bhagavad Gita · 8.15

मामुपेत्य पुनर्जन्म दुःखालयमशाश्वतम्।नाप्नुवन्ति महात्मानः संसिद्धिं परमां गताः॥

mām upetya punar janma duḥkhālayam aśhāśhvatam nāpnuvanti mahātmānaḥ saṁsiddhiṁ paramāṁ gatāḥ

Having attained Me, the great souls are not born again in this transient world of suffering. They have reached the supreme perfection.
