Determination is how your body is built to take life in: how you receive nourishment, and underneath that, how you absorb information and experience. It is the first of the four deep transformations in your design, and it works from the body upward. It is carried by the unconscious side of your chart, the part that runs your physical vehicle without ever asking your opinion. When you take things in the way your system is actually built to receive them, physical resistance drops, your energy steadies, and everything downstream, from mood to mental clarity, gets easier. Ra framed it as an experiment rather than a commandment, and it only works on top of living by your Strategy and Authority: if your Authority says no to a change, do not make it.
Your colour is Thirst, and it sits in the lower half of the six, which means it is genuinely about the substance: what actually goes into you. Thirst concerns one specific property of what you consume, and that property is temperature. Your body reads the heat or the cold of whatever arrives, food and drink alike, and that reading shapes how well it can break the thing down. This is not a matter of what you happen to enjoy. It is the setting your metabolism is already running on.
Your arrow points left, the focused, strategic side. Do not leave the temperature of your food and drink to whatever happens to be put in front of you. Choose warm on purpose, start the day with something heated, and leave the ice out. Ra suggested the same body does better with warmth in general, so cold showers are not your friend and a sauna may well be.
The same shape governs how you take in everything else. Warmth in the conditions helps you absorb: a warm room, a warm voice, a subject with real heat in it. Cold material delivered coldly will not go in however hard you push at it. How your body digests is the same shape as how your mind decides. Warm the conditions first, and what you need to take in will go down far more easily.
