Gita Chapter 15.16 to 15.20

Dwaavimau purushau loke ksharashchaakshara eva cha;
Ksharah sarvaani bhootaani kootastho’kshara uchyate.
16. Two Purushas there are in this world, the perishable and the imperishable. All beings are the perishable, and the Kutastha is called the imperishable.

Uttamah purushastwanyah paramaatmetyudaahritah;
Yo lokatrayamaavishya bibhartyavyaya ishwarah.
17. But distinct is the Supreme Purusha called the highest Self, the indestructible Lord who, pervading the three worlds, sustains them.

Yasmaat ksharam ateeto’hamaksharaadapi chottamah;
Ato’smi loke vede cha prathitah purushottamah.

18. As I transcend the perishable and am even higher than the imperishable, I am declared as the highest Purusha in the world and in the Vedas. 

Yo maamevam asammoodho jaanaati purushottamam;
Sa sarvavidbhajati maam sarvabhaavena bhaarata.
19. He who, undeluded, knows Me thus as the highest Purusha, he, knowing all, worships Me with his whole being (heart), O Arjuna!

Iti guhyatamam shaastram idamuktam mayaa’nagha;
Etadbuddhwaa buddhimaan syaat kritakrityashcha bhaarata.
20. Thus, this most secret science has been taught by Me, O sinless one! On knowing this, a man becomes wise, and all his duties are accomplished, O Arjuna!

Hari Om Tat Sat

Iti Srimad Bhagavadgeetaasoopanishatsu Brahmavidyaayaam

Yogashaastre Sri Krishnaarjunasamvaade

Purushottamayogo Naama Panchadasho’dhyaayah

Thus in the Upanishads of the glorious Bhagavad Gita, the science of the Eternal, the

scripture of Yoga, the dialogue between Sri Krishna and Arjuna, ends the fifteenth discourse

entitled:

“The Yoga of the Supreme Spirit”

Gita Chapter 15.11 to 15.15

Yatanto yoginashchainam pashyantyaatmanyavasthitam;
Yatanto’pyakritaatmaano nainam pashyantyachetasah.
11. The Yogis striving (for perfection) behold Him dwelling in the Self; but, the unrefined and unintelligent, even though striving, see Him not.

Yadaadityagatam tejo jagad bhaasayate’khilam;
Yacchandramasi yacchaagnau tattejo viddhi maamakam.
12. That light which residing in the sun, illumines the whole world, that which is in the moon and in the fire—know that light to be Mine.

Gaam aavishya cha bhootaani dhaarayaamyaham ojasaa;
Pushnaami chaushadheeh sarvaah somo bhootwaa rasaatmakah.
13. Permeating the earth I support all beings by (My) energy; and, having become the watery moon, I nourish all herbs.

Aham vaishwaanaro bhootwaa praaninaam dehamaashritah;
Praanaapaana samaayuktah pachaamyannam chaturvidham.
14. Having become the fire Vaisvanara, I abide in the body of living beings and, associated with the Prana and Apana, digest the fourfold food.

Sarvasya chaaham hridi sannivishto
Mattah smritir jnaanam apohanam cha;
Vedaischa sarvairahameva vedyo
Vedaantakrid vedavid eva chaaham.
15. And, I am seated in the hearts of all; from Me are memory, knowledge, as well as their absence. I am verily that which has to be known by all the Vedas; I am indeed the author of the Vedanta, and the knower of the Vedas am I.

Gita Chapter 15.06 to 15.10

Na tadbhaasayate sooryo na shashaangko na paavakah;
Yadgatwaa na nivartante taddhaama paramam mama.
6. Neither doth the sun illumine there, nor the moon, nor the fire; having gone thither they return not; that is My supreme abode.

Mamaivaamsho jeevaloke jeevabhootah sanaatanah;
Manah shashthaaneendriyaani prakritisthaani karshati.
7. An eternal portion of Myself having become a living soul in the world of life, draws to (itself) the (five) senses with the mind for the sixth, abiding in Nature.

Shareeram yadavaapnoti yacchaapyutkraamateeshwarah;
Griheetwaitaani samyaati vaayurgandhaanivaashayaat.
8. When the Lord obtains a body and when He leaves it, He takes these and goes (with them) as the wind takes the scents from their seats (flowers, etc.).

Shrotram chakshuh sparshanam cha rasanam ghraanameva cha;
Adhishthaaya manashchaayam vishayaanupasevate.
9. Presiding over the ear, the eye, touch, taste and smell, as well as the mind, he enjoys the objects of the senses.

Utkraamantam sthitam vaapi bhunjaanam vaa gunaanvitam;
Vimoodhaa naanupashyanti pashyanti jnaanachakshushah.
10. The deluded do not see Him who departs, stays and enjoys; but they who possess the eye of knowledge behold Him.
