As fire is shrouded by smoke, a mirror is covered by dust, and a child is enveloped by the womb, so is the universe enveloped in desire.
Translated by Shri Purohit Swami
As fire is enveloped by smoke, as a mirror is covered by dust, and as an embryo is surrounded by the amniotic sac, so is this enveloped by that.
