Shaṭpraśnopaniṣat Bhāshya (षट्प्रश्नोपनिषद्भाष्यं)

ādityo ha vai bāhyaḥ prāṇa udayaty eṣa hy enaṃ cākṣuṣaṃ prāṇam anugṛhṇānaḥ। pṛthivyāṃ yā devatā saiṣā puruṣasyāpānam avaṣṭabhya antarā yad ākāśaḥ sa samāno vāyur vyānaḥ। tejo ha vā udānaḥ। tasmād upaśāntatejāḥ punarbhavam indriyaiḥ manasi sampadyamānaiḥ ॥6॥

The sun is considered the external prāṇa that rises and supports the visual prāṇa. The deity on earth, she, supports the 'apānam' i.e. downward breath, of a person. The space in between is the 'samāna' i.e. equalizing prāṇa, that is diffusing air. Fire is seen as 'udānaḥ' i.e. the upward breath. Therefore, when the fire is subdued, rebirth happens as the senses merge into the mind.

बहुचित्रजगद्बहुधाकरणात् परशक्तिरनन्तगुणः परमः ।
सुखरूपममुष्य पदं परमं स्मरतस्तु भविष्यति तत्सततम् ॥
"The one who has created this variegated vast universe with varied forms has infinite power and is of infinite auspicious qualities. He certainly bestows the highest state of bliss to those who meditate on his ever happy essence." -Dwādasha stōtra 4.3
