Will it be 'good', to be always 'shrewd'...?

No! Certainly, it won't be...!

Will it be 'good', to be always 'innocent'...?

No! Certainly, it won't be...!

Will it be 'good' of NOT knowing to be 'shrewd'...?

No! Certainly, it won't be...!

Will it be 'good' of NOT knowing to be 'innocent'...?

No! Certainly, it won't be...!

Then what else will be 'good'...?

It all depends on the situations, circumstances, time, etc.

When to be innocent in the society...?

When to be shrewd in the society...?

We must KNOW both!

If we know to 'be' both, 
if we have faith in us and
if we have faith in Lord, 
we could be...!

Should we be as a snake or dove...?

Let us be just human beings...!
