Isvayasa 16 Translation Fantasia

pūşannekarşe yama sūrya prājāpatya vyūha raśmin samūha, tejo yatte rūpaṁ 

kalyāņatamam tatte paśyāmi yo'sāvasau puruṣaḥ so'hamasmi.

पूषन् O! Pūsan; एकर्षे Controller; सूर्य O! sole seer; यम Ο! O! Sūrya; प्राजापत्य O! Son of rays; समूह Thy; रूपम् gather form; that; ते - thy; this; असौ this; पुरुषः Prajāpati; व्यूह - disperse; रश्मीन् up; तेजः - light; यत् what; ते कल्याणतमम् most auspicious; तत् पश्यामि - (I) see; यः who; असौ Puruşa; सः - he; अहम् - I; अस्मि am

O! Pūşan (sun, nourisher), O! sole seer, O! controller of all, O! Sūrya, O! son of Prajāpati, disperse Thy rays and gather up Thy burning light, I behold Thy glorious form, the Puruşa within Thee, He am I.

It is to be noted that Lord Sun was the Guru of Sage Yājñavalkya, the compiler of the Śukla Yajurveda Samhitā; and Īśāvāsyopaniṣad belongs to it. The samhita itself was taught to him by Lord Sun. The Sun is the greatest nourisher, disinfector, the 'great filler' who fills life with flavour. 'By Thy grace may I reach nearer the Iśa who indwells everywhere, including Thee,' seems to be here, the cry of the heart at meditation.

Before this final experience of oneness 'He am I', we have been shown how there is a lower state of realisation that 'I behold Thy glorious form', wherein the ego still remains, experiencing a divine exaltation. This state is called savikalpa samādhi. This precedes the final stage of the total end of the ego when the seeker rediscovers himself to be the sought the supreme Self. This stage of experience of oneness is called the nirvikalpa samādhi.

~Chinmayananda

O Pushan! O Sun, sole traveller of the heavens, controller of all, son of Prajapati, withdraw Thy rays and gather up Thy burning effulgence. Now through Thy Grace I behold Thy blessed and glorious form. The Purusha (Effulgent Being) who dwells within Thee, I am He. 

Here the sun, who is the giver of all light, is used as the symbol of the Infinite, giver of all wisdom. The seeker after Truth prays to the Effulgent One to control His dazzling rays, that his eyes, no longer blinded by them, may behold the Truth. Having perceived It, he proclaims: "Now I see that that Effulgent Being and I are one and the same, and my delusion is destroyed." By the light of Truth he is able to discriminate between the real and the unreal, and the knowledge thus gained convinces him that he is one with the Supreme; that there is no difference between himself and the Supreme Truth

~Paramananda

O Nourisher, lone Traveller of the sky! Controller! O Sun, Offspring of Prajapati! Gather Your rays; withdraw Your light. I would see, through Your grace, that form of Yours which is the fairest. I am indeed He, that Purusha, who dwells there.

PURUSHA: Lit., Person. It also refers to the Godhead, who lies in the hearts of all, or who fills the whole universe with life and consciousness.
