Seven small balls of clay, as big as jujube kernels, are infinitely smaller than the earth. So with the Ariyan disciple - when he has won understanding, the dukkha that remains is infinitely smaller than that which he has destroyed. S. ii.135f.; repeated at S. v.462f.

The same as the above. S. ii.136.

Incalculable is samsāra. The number of parents a man has had would be greater than the number of balls, each the size of a kola (jujube) kernel, that could be made of the clay of the earth. S. ii.179.
