The main characteristic of Tantra (spiritual expression) is that it represents mainly vigour. It represents a pactless fight. Where there is no fight there is no sadhana (spiritual practice).

It is impossible to conquer a crude idea and to replace it by a subtle idea without a fight. It is not possible without spiritual practice. Hence, Tantra is not only a fight, it is an all-round fight. It is not only an external or an internal fight, it is simultaneously both.

When a spiritual aspirant tries to enlarge his mind, naturally debasing forces become very active. The aspirant is to enlarge his mind and spirit by fighting at each and every step, each and every stage of life.

In his mind there will be those two belligerent forces. That is, the spiritual force and the debasing material force will start fighting amongst each other in the mind. One force will try to exalt you towards the Supreme Self, another force will want to degrade you, goad you towards crude materialism.

He who wants to keep himself away from fight is unknowingly committing suicide, mental and spiritual suicide. Each and every man should be ready for fight – fight in the mental stratum, fight in each and every stratum of life. This is Tantra.
