There is a mitzvah to be happy always, b’simchah tamid.
But how can that be? Is there anything which is “always,” that never changes?
Yes. Hashem is always. He is unchanging and steady.
Simchah doesn’t mean laughing and dancing, it means being in a state of contentment, it means serenity and acceptance.
I’m b’simchah when I recognize that He – Who is always – is in charge, and it’s not about my will, but His.
B’simchah, happy, tamid, always.
