The Fire on the Fiery mountains represents the volatile nature of emotions, which are obstacles on the way.

Not yet settled (#64 Unsettled ䷿) means the earthly and the celestial are separated. In the hexagram, Fire ☲ is above and Water ☵ is below; Fire and Water are in different places. Water flows downward and fire flames upward, so water cannot control fire and fire cannot heat water-innate knowledge turns into artificial knowledge and temper flares; innate capacity turns into artificial capacity and greed arises. -- Liu Yiming, The Taoist I Ching, Mixed Hexagrams # 63 Settled and #64 Unsettled

Being settled (Hexagrams #63 ䷾) means the earthly and the celestial are completed. In the hexagram, Water ☵ is above and Fire ☲ is below; with fire, water is not cold, and with water, fire is not hot. Heaven and earth constitute the body, water and fire constitute the function; innate knowledge and innate capacity, creativity and receptivity, are as one, spirit and vitality cleave to each other, and the celestial and the earthly combine-thus it is called stabilization. -- Liu Yiming, The Taoist I Ching, Mixed Hexagrams # 63 Settled and #64 Unsettled

Tarot card XXI, the Mystical Female

The Valley Spirit represents the presence of the Original Spirit or Higher Self. When the Higher Self is present, although it is still connected to the lower self and in the body, it is psychologically speaking separate from the lower self. When this state deepens, there is a distance between itself and the lower self, and the lower self is no longer experienced as 'I'. What is now experienced as 'I', is that which observes the lower self. What the lower self experiences is percieved by the Higher Self, as the echo of voices in a valley . Therefore the text says that one definitely hears it and yet it is not oneself that hears it. It is the lower self that hears it, and one observes it from distance.

Apart from the pulling and hauling stands what I am,
stands amused, complacent, compassionating,
idle, unitary, both in and out of the game
and watching and wondering at it.
-- Walt Whitman (19th c. American poet)
