A pure Ass has a Burden

An Ass can be enlightened and carry that burden well in benefilting all other beings.

Burden is something we carry, literally and figuratively.

Freedom is ceasing to carry burdens, especially other people's burdens.

Let others carry their own burdens but help them see that they should not carry other people's burdens.

This is difficult and dangerous spiritual activity. Go slowly and gently or you will increase your own burden.
