When someone dies,
We believe s/he would go to heavens,
And meet the 'God/s' and 'Goddesses',
Who we might have decided,
And we put flowers on her/his body.
When the dead body 'meets' the 'God',
The same flowers are 'offered',
To the 'God', and our respect to him,
And our message of worshipping him,
are conveyed by the dead 'person'.
Isn't it a beautiful arrangement!
