Fasting leads to the total equilibrium and harmony of our mental, spiritual and physical selves. If our physical self becomes doninant, it is good to reduce physical activity so as to liberate the spirit and establish the equilibrium of spiritual purity. Even the stoics taught that spiritual purity leads to the harmony of man's entire being.
Fasting gives us back our lost equilibrium and brings into harmony our mind, our soul and our body Abstainging from excessive food results in the lightening of the capabilities of the mind and the soul. Food is conducive to sleep rather than activity, be it physical or mental.
Some exerts from a book I saw online. It gave me hope. Maybe for you to.
