21 Gms Or Three Quarter Of An Ounce Poem by Sadashivan Nair

Just soul of 3 quarters of an ounce:
Exist in earthly body,
Accomplish planned tasks,
Generate energy and leave;
Endure pain and joy,
During all my life;
Negative and positive both prevail,
React to ambiance surrounding mine,
Life was full of joy and sorrow,
Until I relinquished the body;
Caring friends and kins,
All accompanied up to burial,
Tears in eyes, gesturing bye;
But none knows I still exist,
Perch in hearts and ambiance;
Why and who am I?
