There are ten kinds of inner winds—five root winds and five branch winds. We cannot sense some of the inner winds, but they do exist. In relative truth, these winds can sustain our body. If something goes wrong with the winds or they are lost, our body will be affected to different degrees.

Tantra has discussed many signs of death, of which some appear physically, some in dreams, and others emotionally.

The reason for the different signs is this: when death is near, the first problem is the gradual weakening of the winds until it comes to a complete stop; we usually don’t feel it, but because winds and mind are closely related, problems will begin to show up in some parts of the body, in dreams, or with our emotions. Although the time remaining until actual death may be long or short, these are all signs of death.

Inner winds at the deep level means movement of consciousness. Although there is no obvious movement in alaya consciousness, the mind which is born of alaya consciousness is subject to fluctuations—the arising, continuum, and ceasing of mind consciousness are also winds.
