5.45.15

evaṃ devo mahātmā sa pāvakaṃ puruṣo giran |
yo vai taṃ puruṣaṃ veda tasyehātmā na riṣyate |
yoginastaṃ prapaśyanti bhagavantaṃ sanātanam || 15 ||

The Supreme Soul endued with four legs, called respectively Waking, Dream, profound Sleep, and Turiya, like unto a swan, treading above the unfathomable ocean of worldly affairs doth not put forth one leg that is hid deep. Unto him that beholdeth that leg (viz., Turiya) as put forth for the purpose of guiding the other three, both death and emancipation are the same. That Eternal One endued with Divinity is beheld by Yogins (by their mental eye). Of the measure of the thumb, ever Full, and different from this eternal organism, coming in contact with the Vital airs, the Will, the Intellect, and the ten Senses, it moveth to and fro. That Supreme Controller, worthy of reverential hymns, capable of everything when vested with accidents and the prime cause of everything, is manifest as Knowledge in creature-Souls. Fools alone do not behold him; that Eternal One endued with Divinity is beheld by Yogins (by their mental eye). Among individuals there are those that have obtained the mastery of their minds, and those that have not. Yet in all men the Supreme Soul may be seen equally. Indeed, it resideth equally in him that is emancipate and in him that is not, with only this difference that they that are emancipate obtain honey flowing in a thick jet. That Eternal One endued with Divinity is beheld by Yogins (by their mental eye). When one maketh life's Sojourn, having attained to the knowledge of Self and Not-Self, then it matters little whether his Agni-hotra is performed or not.

O monarch, let not such words as 'I am thy servant' fall from their lips. The Supreme Soul hath another name, viz., Pure Knowledge. They only that have restrained their minds obtain Him. That Eternal One endued with Divinity is beheld by Yogins (by their mental eye). Even such is He. Illustrious and Full, all living creatures are merged into Him. He that knoweth that embodiment of Fullness attaineth to his object (emancipation) even here. That Eternal One endued with Divinity is beheld by Yogins (by their mental eye). That which flieth away stretching forth thousands of wings, yea, if endued with the speed of the mind, must yet come back to the Central Spirit within the living organism (in which the most distant things reside... That Eternal One endued with Divinity) is beheld by Yogins (by their mental eye). His form cannot be an object of sight. They only, that are of pure hearts, can behold him. When one seeketh the good of all, succeedeth in controlling his mind, and never suffereth his heart to be affected by grief, then he is said to have purified his heart. Those again that can abandon the world and all its cares, become immortal. (That Supreme Soul which is undying),--that Eternal One endued with Divinity--is beheld by Yogins (by their mental eye). Like serpents concealing themselves in holes, there are persons who following the dictates of their preceptors, or by their own conduct conceal their vices from scrutiny's gaze.
