Can Solitary Consciousness Separate from the Body?

The body is the physical body, the material form, which pertains to material dharmas. Consciousness is the mind-consciousness, formless and without characteristics, not a material dharma. The two do not separate or unite in any physical sense; concepts such as consciousness leaving or residing within the body are merely expedient expressions for teaching purposes.

Some individuals, upon attaining a slight degree of meditative concentration, may experience the phenomenon of their consciousness separating from the body. They feel as though they are outside their body, numbly and blankly observing their own physical form, while the body continues its activities involving the five aggregates. Those without meditative concentration will not experience this sensation.

At deeper levels of meditative concentration, consciousness can even leave the body to perform tasks. For instance, during the Tang Dynasty, a Zen practitioner often saw other bhikkhus (monks) during his evening meditation who were so hungry they could not straighten their backs. To help them cultivate their meditation effectively, he would hide his physical body where the elder monk could not see it. His consciousness would then go to the kitchen, steal the burnt rice from the bottom of the pot, bring it back to share with the others, and finally return to his body to resume sitting in meditation. Eventually, the elder monk discovered this. Believing that his spiritual attainment was sufficient for him to live alone in the mountains to propagate the Dharma, the elder monk then sent him out of the monastery.

If one cultivates meditative concentration to the Fourth Dhyāna, spiritual powers will manifest. The functions of consciousness become even more potent, enabling it to leave the body or even create multiple manifestations. What is the principle behind a Bodhisattva manifesting countless incarnations? Each of the countless manifestations possesses its own complete set of six consciousnesses, maintaining the activities of different physical bodies. Yet, the eighth consciousness remains the original single one, and the mental faculty (manas) is also the original one. There will not be an additional or multiple mental faculties, for otherwise, it would no longer be the same individual.

Why can there be countless sets of the six consciousnesses distributed across countless physical bodies? Because the six consciousnesses are born from the union of the eighth consciousness and the mental faculty. When meditative concentration is fully perfected, a single thought from the mental faculty causes the eighth consciousness to manifest one or multiple sets of the six consciousnesses. These manifest vividly, representing the mental faculty and the eighth consciousness in performing actions. Therefore, with sufficient meditative concentration, when the mental faculty gives rise to a thought, the isolated mental consciousness can leave to observe itself. I have personally experienced this: I felt my isolated mental consciousness observing me from above my head as I sat on the bed, immersed in sorrow.

Since consciousness is formless and without characteristics, not existing in a physical manner, its relationship with the physical body is not any kind of physical relationship. Sentient beings cannot comprehend this relationship; they do not understand how something formless and without characteristics can exist. They often mistakenly believe it resides in a specific part of the body. In truth, consciousness does not dwell in any particular location within the physical body—not inside, outside, or within it. Inside, outside, and within are physical concepts, whereas consciousness transcends physical concepts.
