Joy

Buddhism

Live in Joy, In love,
Even among those who hate.

Live in joy, In health,
Even among the afflicted.

Live in joy, In peace,
Even among the troubled.

Look within. Be still.
Free from fear and attachment,
Know the sweet joy of living in the way.

from the Dhammapada

from Galatians 5:22

The one who loves all intensely begins perceiving in all living beings a part of himself…
He becomes a lover of all, a part and parcel of the Universal Joy.
He flows with the stream of happiness, and is enriched by each soul.

from the Yajur Veda

Sufism

Patience is the key to joy.
