“Happiness is an attitude to life as a whole, while joy lives in the moment… Happiness is something you pursue. But joy is not. It discovers you. It has to do with a sense of connection to other people or to God. It comes from a different realm than happiness. It is a social emotion. It is the exhilaration we feel when we merge with others. It is the redemption of solitude…
Hence Moses’ insistence that the capacity for joy is what gives the Jewish people the strength to endure. Without it, we become vulnerable to the multiple disasters set out in the curses in our parsha.
Celebrating together binds us as a people: that and the gratitude and humility that come from seeing our achievements not as self-made but as the blessings of God. The pursuit of happiness can lead, ultimately, to self-regard and indifference to the sufferings of others. It can lead to risk-averse behaviour and a failure to ‘dare greatly.’
Not so, joy. Joy connects us to others and to God. Joy is the ability to celebrate life as such, knowing that whatever tomorrow may bring, we are here today, under God’s heaven, in the universe He made, to which He has invited us as His guests.”
