The spirit soul, the living entity, has no death, for he is eternal and inexhaustible. Being free from material contamination, he can go anywhere in the material or spiritual worlds. He is fully aware and completely different from the material body, but because of being misled by misuse of his slight independence, he is obliged to accept subtle and gross bodies created by the material energy and thus be subjected to so-called material happiness and distress. Therefore, no one should lament for the passing of the spirit soul from the body.
Srimad Bhagavata Purana

नित्य आत्माव्ययः शुद्धः सर्वगः सर्ववित्परः । धत्तेऽसावात्मनो लिङ्गं मायया विसृजन् गुणान्
nitya ātmāvyayaḥ śuddhaḥ sarvagaḥ sarvavitparaḥ | dhatte'sāvātmano liṅgaṃ māyayā visṛjan guṇān
