The Buddha recognised that all physical bodies are born, exist and then die. This logical observation serves as the foundation of the Buddha’s Teaching. It is an inevitable process that every living-being must experience. An individual will be born, will live their life in any number of ways, and will then pass away through natural (old age) or unnatural (illness, injury or accident, etc) causes. According to the Buddha, the state of an individual’s mind is responsible for the ‘willed’ (volitional) actions performed through the body. The frequency of these decisions can be ‘healing’ and ‘compassionate’ or ‘debilitating’ and ‘horrible’ - it all depends upon the past conditioning (karma) of the individual mind (and body).
By permanently ‘stilling’ (and ‘expanding’) the mind, all karmic production is eradicated. This is a moment of karmic purification of mind and body. The ‘ridge-pole of ignorance is destroyed forever’ as the Buddha states in the Dhammapada. This is the experience of nirvana whilst still inhabiting a human-body – and when death arrives the body will ‘fall away’ - revealing the state of experiencing ‘nirvana’ without inhabiting a body. Through adhering to the Vinaya Discipline – this strict regulation of the mind and body in the environment has a beneficial effect with regards to health. This is because every rule is designed by the Buddha to ‘remove’ a particular negative (karmic) trait that causes ‘suffering’ in the mind and body of the individual and which permeates out into the environment if not ‘checked’ through the deployment of purposeful discipline.
This is how the Buddha strives to reduce suffering in the mind and body of the individual (and in the world). This process is cemented by emptying the mind of greed, hatred and delusion – whilst directly ‘perceiving’ the empty essence of the perceiving (and ‘non-perceiving’) mind. This is how the Buddha strives to eradicate all ‘illnesses’ (and illness generating ‘delusion’) from the mind, body and environment through the application of a strict discipline. This is why Master Xu Yun (1840-1959) was of the opinion that the Vinaya Discipline is a vital (foundational) element of ALL genuine schools of Buddhism – and refused to follow the example of Japan in ‘abolishing’ the Vinaya Discipline as a guide for monks and nuns. If a person wants to live longer and in a healthier manner – then follow the Vinaya Discipline!
