440. Nothing enters into me

Nothing enters into me.
Humility does not enter into me
Even when I eat my blades of grass.

Devotion does not enter into me
Even when I place my head at the feet of my Master.

Sincerity does not enter into me
Even though every morning I go to church.

Purity does not enter into me
Even though I wash myself for hours.
Am I not something?
