[Advaita-l] Gita 2.16 Simpler Meaning

[Bhaskar YR]

sat: something which is auspicious
asat : something which inauspicious

praNAms
Hare Krishna

Sri bhAshyakAra explains what is sat and what is asat in his taittireeya up. bhAshya (2.1.1).  As per this bhAshya, that which once determined will remain as such 
always is Satyam and  that which does not remain the same as once determined/perceived  is asatyaM. (Tai.Bh. 2.1.1) but has he said this changing colour is amangala ??  I don't think so.  

Hari Hari Hari Bol!!!
