Gita Chapter 13.21 to 13.25

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.

Purushah prakritistho hi bhungkte prakritijaan gunaan;
Kaaranam gunasango’sya sadasadyoni janmasu.
22. The soul seated in Nature experiences the qualities born of Nature; attachment to the qualities is the cause of his birth in good and evil wombs.

Upadrashtaanumantaa cha bhartaa bhoktaa maheshwarah;
Paramaatmeti chaapyukto dehe’smin purushah parah.
23. The Supreme Soul in this body is also called the spectator, the permitter, the supporter, the enjoyer, the great Lord and the Supreme Self.

Ya evam vetti purusham prakritim cha gunaih saha;
Sarvathaa vartamaano’pi na sa bhooyo’bhijaayate.
24. He who thus knows Spirit and Matter, together with the qualities, in whatever condition he may be, he is not reborn.

Dhyaanenaatmani pashyanti kechidaatmaanamaatmanaa;
Anye saankhyena yogena karmayogena chaapare.
25. Some by meditation behold the Self in the Self by the Self, others by the Yoga of knowledge, and others by the Yoga of action.

Gita Chapter 13.16 to 13.20

Bahirantashcha bhootaanaam acharam charameva cha;
Sookshmatwaat tadavijneyam doorastham chaantike cha tat.
16. Without and within (all) beings, the unmoving and also the moving; because of His subtlety, unknowable; and near and far away is That.

Avibhaktam cha bhooteshu vibhaktamiva cha sthitam;
Bhootabhartru cha tajjneyam grasishnu prabhavishnu cha.
17. And undivided, yet He exists as if divided in beings; He is to be known as the supporter of beings; He devours and He generates also.

Jyotishaamapi tajjyotistamasah paramuchyate;
Jnaanam jneyam jnaanagamyam hridi sarvasya vishthitam.
18. That, the Light of all lights, is beyond darkness; it is said to be knowledge, the Knowable and the goal of knowledge, seated in the hearts of all.

Iti kshetram tathaa jnaanam jneyam choktam samaasatah;
Madbhakta etadvijnaaya madbhaavaayopapadyate.
19. Thus the Field as well as knowledge and the Knowable have been briefly stated. My devotee, knowing this, enters into My Being.

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.
