When actions are based on valuing life, then one attains one’s nature. If not, then one loses one’s nature. . The common rulers [su zhu , see chapter four] harm their essential nature, so all their actions result in loss and defeat. Their ears cannot be satiated, their eyes satisﬁed, or their mouths ﬁlled. 102 Suspicion of the senses appeared in a late fourth-century text discovered at Guodian, where it is part of a larger concern about the fate of the body under the threat of stress and exertion: For agitation of the heart/mind, longing is the worst.
Each of these zones is distinguished by the most reﬁned beings that appear within it. 33 Thus, the embodied self emerges as the central focus within an extended spatial ﬁeld, a ﬁeld linked together through the movement of a common energy. Having begun with the self and its relation to the world, the text then devotes several passages to the manner in which the vital energies that ﬁll the cosmos can be secured within the body. This is followed by the ﬁrst reference to the heart/mind (xin ) at the core of the person: All proper forms [xing ] of the mind Spontaneously ﬁll, spontaneously suffuse [with vital energies], Spontaneously give life [sheng], spontaneously complete [cheng].
67 This speech by a minister in charge of the kitchen asserts that the body’s energies inform its intent, so that the ruler’s failings result from inadequacies of diet. 69 The idea that the body’s energies guide its intent also appears in military contexts. One ruler argues that the ancient rules of chivalrous combat dictated that one should not strike an opponent twice, kill the aged, attack when the enemy is penned in a narrow deﬁle, or launch an offensive when he has not yet formed his lines.
