Tapas is described as the form of Divine energy which exists within the human body. It is portrayed as a heightened aspiration that absorbs the subsidiary interests and attachments. Tapa is the real interest and assimilation in the spiritual life, the heat of spiritual inquiry and aspiration.

Tapas , the Sanskrit word is derived from "tap" which denotes " to consume by heat", "to mortify the body" or "to undergo severe penance". Tapas connote the concentration of senses and the mind and dexterity of will and thought.

Relating the in depth fire of the soul with the life-fire in the body, Tapas finds expression through heart and leads to liberate the soul from the fantasy and smoothens the way towards self realization. This is depicted as the real inner movement of Tapas. Being the supreme power of speech, goddess Bhairavi represents the real wrath and anger. Goddess Bhairavi, the real energy of Tapas which is her power of purification and transformation, guides the true Tapas. Tapas is practiced by those who are seeking knowledge and lead a life of Brahmacharya. Goddess Bhairavi controls the senses, the emotions and wandering thoughts and guides the attempt of any spiritual concentration in the right way. Through Tapas, the control over mind is possible and the silence of mind can be achieved.

Tapas is described as the process without which nothing on the spiritual path can be attained.
