Sankaracarya's Vivekachudamani 417

समूलमेतत्परिदाह्य वन्हौ

सदात्मनि ब्रह्मणि निर्विकल्पे ।

ततः स्वयं नित्यविशुद्धबोधा

नन्दात्मना तिष्ठति विद्वरिष्ठः ॥

samūlametatparidāhya vanhau

sadātmani brahmaṇi nirvikalpe |

tataḥ svayaṃ nityaviśuddhabodhā

nandātmanā tiṣṭhati vidvariṣṭhaḥ ||

(Sankaracarya's Vivekachudamani 417)

Burning all this, root and all, in the fire of Brahman, the Eternal, Absolute Self, the truly wise remain alone, established as the pure, eternal, enlightened, Self blissfulness.

Although we are living in an illusionary world, yet our constitutional position is to understand that we are souls. To understand the truth we need to learn the truth from the Vedas without distraction. Either the soul stay or leave one's body we shouldn't lament. It's best to burn all the attachments that we have by the fire of Brahman to establish eternally and being blissful in the lotus feet of Paramatma.
