Free of the materiality of the world,
Free of mental anguish,
Free of emotions,
But
I'll be not a human then.

I must be alive.
Feeling the materiality of the world,
Feeling mental anguish,
And all emotions,
Whether they are bad
Whether they are good.

There are no "bad" emotions, really.
Disappointment, grudge or sorrow
Without them (and others) I wouldn't know
Such "good" ones
As happiness, joy and love.
