Every conditioned soul receives a different type of body according to his work, and when the engagement is finished the body is finished. Although the spirit soul is situated in subtle and gross material bodies in different forms of life, he is not bound by them, for he is always understood to be completely different from the manifested body.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
भूतानि तैस्तैर्निजयोनिकर्मभि- र्भवन्ति काले न भवन्ति सर्वशः । न तत्र हात्मा प्रकृतावपि स्थित- स्तस्या गुणैरन्यतमो निबध्यते
bhūtāni taistairnijayonikarmabhi- rbhavanti kāle na bhavanti sarvaśaḥ | na tatra hātmā prakṛtāvapi sthita- stasyā guṇairanyatamo nibadhyate
