What satisfies the needs of the body is a necessity. The needs are those that satisfy the sense organs. Our life's first element is body and the second element is sense organs. Ornamentation is not a need of the body. It is a demand of the sense organs. Hearing music, seeing movies, eating tasteful food, experiencing pleasure, giving contact - these are the demands of the sense organs.
Mahavira and spiritual teachers did not reject these demands. They accepted that these are demands, and men and women, the social beings, exist within the bounds of this reality. That is why these were permitted to be satisfied.
Beyond these, there are the demands of the mind. These demands are not directly relevant to the body, but if the demands of the mind are suppressed, it can create mental disorders or aberrations. It is therefore appropriate to satisfy the demands of the mind.
Going beyond this, it is also necessary to maintain healthy relations with the family and with other members of the society.
Expanding the family and establishing social relationships is also a necessity. Getting married, producing progeny and satisfying the sense organs have all been classified by Vinayvijayaji. The Acharya has presented the entire visualization of Mahavira.
