According to the teachings, what is the true nature of the Soul and its relationship with action?

Chapter 8 explains that the Soul, or Atman, is fundamentally a non-doer. The body, senses, mind, and intellect are described as mere adjuncts or 'upadhis'. It is only through these instruments that the Soul mistakenly attributes the concept of 'doership' to itself. Similarly, its state of being an 'enjoyer' is conditional and not its inherent nature. The text asserts that scripture, logic, and reasoning all serve as proofs for this core principle, urging one to know their own essence and remain actionless by handing over actions to the intellect.
