Bhagavad-Gita The Song Divine Chapter 13 (stanza 23-34)

He, who thus knows the Purusa (spirit) and Prakrti (Nature) together with the Gunas - even though performing his duties in every-way, is not born again. ……………… (23)
Some by meditation behold the supreme Spirit in the heart with the help of their refined and sharp intellect; others realize it through the discipline of Knowledge, and still others, through the discipline of Action, i.e., Karma Yoga. ………. (24)
Other dull-witted person, however, not knowing thus, worship even as they have heard from others i.e., the knower's of truth; and even those who are thus devoted to what they have heard, are able to cross the ocean of mundane existence in the shape of death. …. (25)
Arjun, whatsoever being, the moving or unmoving is born, know it as emanated through the union of Ksetra (Matter) and the Ksetrajna (Spirit). ……… (26)
He alone truly seed; who sees the supreme Lord as imperishable and abiding equally in all perishable beings, both animate and inanimate. ………….. (27)
For, by seeing the Supreme Lord equally present in all, he does not kill the Self by himself, and therby attains the supreme state. …………….. (28)
He who sees that all actions are performed in every-way by nature (Prakrti)  and the Self as the non-doer, he alone verily sees. …………….. (29)
The moment man perceives the diversified existence of beings as rooted in the one supreme Spirit, and the spreading forth of all beings from the same, that very moment he attains Brahma (who is Truth, Consciousness and Bliss solidified). ………. (30)
Arjun, being without beginning and without attributes, this indestructible supreme Spirit, though dwelling in the body, in fact does nothing, nor gets tainted. ……………… (31)
As the all-pervading ether is not contaminated by reason of its subtlety, though permeating the body, the Self is not affected by the attributes of the body due to Its attribute less character.  ……………. (32)
Arjun, as the one sun illumines this entire universe, so the one Atma (Spirit) illumines the whole Ksetra (Field). …………. (33)
Those who thus perceive with the eye of wisdom, the difference between the Ksetra and Ksetrajna, and the phenomenon of liberation from Prakrti with her evolutes, reach the supreme eternal Spirit.  …………….. (34)
Thus, in the Upanishad sung by the Lord, the Science of Brahma, the scripture of Yoga, the dialogue between Sri Krishna and Arjun, ends the thirteenth chapter entitled "The Yoga of Discrimination between the Field and the Knower of the Field."
