1 Gita Sloka  Every Day - Chapter 18 - Moksha Sanyasa Yoga - Sloka 8

Thought at Birth

Dukham iti eva yat karma kaya klesha bhayat tyajet I

Sa krutva rajasam tyagam na eva tyaga phalam labhet II sloka 8

दुखं इति एव यत् कर्म काय क्लेश भयात् त्यजेत् I 

स कृत्वा राजसं त्यागं न एव त्याग फलम् लभेत् II श्लोक 8

He who from fear of bodily trouble abandons action, because it is painful, thus performing a rajasika abandonment, obtains no fruit whatsoever.

The karmas prescribed in the shastras, as being helpful for attaining moksha, causes mental tension; because they can be performed only by gathering materials, which is difficult. Further, they produce physical strain and exertion.

So, if a person gives up such karmas like pancha maha yagna; because of fear of physical strain and other difficulties; this is called rajasa tyaga. He will also not get the fruit of such tyaga viz., purity of mind and correct knowledge.
