Mahabharata 5.45.14

5.45.14

ekaṃ pādaṃ notkṣipati salilāddhaṃsa uccaran |
taṃ cetsatatamṛtvijaṃ na mṛtyurnāmṛtaṃ bhavet |
yoginastaṃ prapaśyanti bhagavantaṃ sanātanam || 14 ||

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.
