Even though most of the illnesses seem to be formed from the body, some of them occurred with respect to the mind. All these mind related illnesses can be suppressed by correctly practicing meditation. Also, one can attain Nibbana, which is the cure for all bodily illnesses, by meditating according to Dhamma so that the path to Nibbana would be developed. Even though medicine helps cure the illnesses temporarily, they can regenerate after sometime. However, the disciple who realized Nibbana will free from all illnesses, aging, death, and also from the long journey of birth and death (the Sansara) because Nibbana stops the rebirth. If this is the case, why do you still late to practice meditation and try hard to attain Nibbana?
