"...the soul is a power that is free. "

If one were to combine the meaning of yesterday's excerpt with the two for today, there could be a "formula" created about our Nature as humans:

SOUL —> MIND —> SENSES

"Now concerning mental faculties, they are in truth of the inherent properties of the soul, even as the radiation of light is the essential property of the sun....It is through the power of the soul that the mind comprehendeth, imagineth and exerteth its influence, whilst the soul is a power that is free. The mind comprehendeth the abstract by the aid of the concrete, but the soul hath limitless manifestations of its own. The mind is circumscribed, the soul limitless. It is by the aid of such senses as those of sight, hearing, taste, smell and touch, that the mind comprehendeth, whereas the soul is free from all agencies."

‘Abdu’l-Bahá: Tablet to August Forel, p. 8

"....regarding the question whether the faculties of the mind and the human soul are one and the same. These faculties are but the inherent properties of the soul, such as the power of imagination, of thought, of understanding; powers that are the essential requisites of the reality of man, even as the solar ray is the inherent property of the sun. The temple of man is like unto a mirror, his soul is as the sun, and his mental faculties even as the rays that emanate from that source of light. The ray may cease to fall upon the mirror, but it can in no wise be dissociated from the sun."

‘Abdu’l-Bahá: Tablet to August Forel, pp. 24-25
