Acquired Intellect sprouts from one's knowledge and experience, as apart from the acquired skills in the other two Houses of Arts, but very crucial to the achievement of higher learning. Hard Strength refers to one's physical strength. Soft Strength is the subtle force or dexterity that enables one to manipulate and reflex with speed and accuracy. Consider the hardness of iron and the softness of silk. Both are hard to break.
Endurance is the power of continuing under hardship without being overcome.
Substantial Perception refers to the acuteness and sensitivity of sight, hearing, taste, smell, and touch. Insubstantial Perception refers to other extra sensory perceptions like feeling people's mind or emotion, direction sense, astral sense. The Aspect of Hard Strength also applies to the beings of Heaven and Earth. However, the three domains use different scales of physical quantities. A man that has a value of 9 is fantasy.
