Prakritim purusham chaiva viddhyaanaadee ubhaavapi;
Vikaaraamshcha gunaamshchaiva viddhi prakritisambhavaan.
20. Know thou that Nature and Spirit are beginningless; and know also that all
modifications and qualities are born of Nature.
Kaaryakaaranakartrutwe hetuh prakritiruchyate;
Purushah sukhaduhkhaanaam bhoktritwe heturuchyate.
21. In the production of the effect and the cause, Nature (matter) is said to be the cause; in
the experience of pleasure and pain, the soul is said to be the cause.
