When the Supreme Personality of Godhead creates different types of bodies, offering a particular body to each living entity according to his character and fruitive actions, the Lord revives all the qualities of material nature — sattva-guṇa, rajo-guṇa and tamo-guṇa. Then, as the Supersoul, He enters each body and influences the qualities of creation, maintenance and annihilation, using sattva-guṇa for maintenance, rajo-guṇa for creation and tamo-guṇa for annihilation.

यदा सिसृक्षुः पुर आत्मनः परो रजः सृजत्येष पृथक् स्वमायया । सत्त्वं विचित्रासु रिरंसुरीश्वरः शयिष्यमाणस्तम ईरयत्यसौ
yadā sisṛkṣuḥ pura ātmanaḥ paro rajaḥ sṛjatyeṣa pṛthak svamāyayā | sattvaṃ vicitrāsu riraṃsurīśvaraḥ śayiṣyamāṇastama īrayatyasau
