Who is a Tapasvi?

The definition of Tapas is there in Valmiki Ramayana. I was very much inspired by it when I read it first time. Such a beautiful and meaningful definition it was.
Tapas as explained is a conscious and continual effort. One who does Tapas becomes one with the self and would be called as Yogi. Valmiki classifies tapas into three kinds of efforts. Sharirika(Effort put by bodily actions), Vachika(Effort put in speech) and Manasika(Effort put within your mind).

देवद्विजगुरुप्राज्ञपूजनं शैचमार्जवं । ब्रह्मचर्यमहिंसा च शारीरतपमुच्यते ।।

This includes a conscious and continual effort 

(a) in respecting Gods, Dvijas (Twice Borns – simply means one who is formally educated), Teachers, Knowledgeable Persons

(b) in being clean and disinfected 

(c) in following Brahmacharya (There is a discourse on what exactly Brahmacharya means in Shanthiparva Mahabharatha, it is not exactly being celibate) 

(d) in not doing violence ( Again Shanthiparva tells the exact meaning of Ahimsa) . 

One who follows these is a Sharira-Tapasvi as it needs a voluntary physical effort to do this.

अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत् | सवाध्यामभ्यसनं चैव वाङमयं तप उच्यते ||

This includes a conscious and continual effort

(a) to speak without being tensed at anytime, 

(b) speaking truth always and speaking truth in a way it is good to listen to. The same is said in manu smriti also – “सत्यं ब्रूयात् प्रियं ब्रूयात् न ब्रूयात्सत्यमप्रियम”. 

(c) to spread through oration, the philosophical and sacred books

One who follows these is a Vachika-Tapasvi as it needs a voluntary effort in speech to do this.

मनः प्रसादः सौम्यत्वं मौनमात्मविनिग्रहः | भावसंशुद्धिरित्येतत्तपो मानसमुच्यते ||

This includes a conscious and continual effort

(a) to present yourself in a pleasant manner with your mind always in content

(b) to be able to control your speech and senses

(c) keeping your mind clean without bad thoughts

One who follows these is a Manasika-Tapasvi as it needs a voluntary effort of mind to do this.

The person who is capable of all three is called a “Tapasvi”.
