1 Gita Sloka  Every Day - Chapter 17 - Shraddhatraya Vibhaga Yoga - Sloka 26

Sadbhave sadhubhave ca sad ity etat prayujyate I

Prasaste karmani tatha sacchabdah partha yujyate II sloka 26

सद भावे साधु भावे च सद इति एतत् प्रयुज्यते I 

प्रशस्ते कर्मणि तथा  सच्छब्द पार्थ युज्यते II श्लोक 26

The word "Sat" is used in the sense of reality and of goodness; and also, O Partha, the word "sat" is used in the sense of an auspicious act. 

Brahman alone is "Sat" and not the Jivatman. Still when a son is born, he is blessed to be ever living. In the worldly parlance, calling the asat as "Sat" is customary. 

Brahman alone is free from blemish. Everything else has some trace of evil in it. The sinful man ought not to be addressed as sinner. For, by doing so the sin in him is further cherished. But by calling him good at all times, the goodness in him is fostered. The attitude of goodness is an effective means to reform the world.This is a great lesson in life to be learnt by all. The word "Sat" is used for this purpose. 

The word "Sat" is used in benediction, approbation and sanction. The discerning ones know for certain that marriage is the cause of downfall of man. It is an inauspicious act in life. Still it is sanctioned and approbated as an auspicious act. The word "Sat" is used in this respect.

Worldly life is ever wrought with evil. On that ground man should not be always harping on the bad. Neither should he assume a pessimistic attitude. There should always be the attempt to make the best of the existing evil. For this purpose also the word "Sat" is used.
