Relationship between the body & mind
Like a bird leaving one nest and flying to another, at death the mind leaves this body and seeks another body.
The relationship between mind and body is explained in great detail in Buddha’s Tantric teachings. It is a relationship between two distinct entities, which for the duration of a life have become associated with each other but which can also exist separately. Buddha compared the mind to a bird and the body to a nest. Like a bird leaving one nest and flying to another, at death the mind leaves this body and seeks another body. Alternatively, mind and body are like a driver and a car, which affect each other but are obviously not the same entity.
Inner Energy Winds
The way in which mind and body are related is explained in terms of inner energy winds. As mentioned before, every mind is said to be ‘mounted’ on an energy wind that gives the mind the power to move towards its object. The winds flow through a network of subtle energy channels in the body, which can be clearly experienced by meditators. These winds serve as an intermediary between formless mind and the gross physical body. Detailed explanations of the inner winds and how they help connect mind and body can be found in the books Clear Light of Bliss and Tantric Grounds and Paths.
