I think that the commercialization of the festival has robbed us of something special and meaningful and made our lives just that little more colorless. When we banish the spiritual dimension from religious festivals like Christmas our need for the nourishment they give forces us to 'invent' fake festivals like Moomba (in Australia) Chingay (here in Singapore) or Macys Parade (in New York) in an attempt to evoke something beyond just 'having a good time.' And such fake festivities are a poor substitute for celebrations like Christmas which have a 2000 year tradition behind them.
When someone says to me 'Happy Holidays' at Christmas I feel like hitting them over the head with my umbrella. Apparently this 'neutralized' and 'secularized' excuse for a blessing is ejaculated so that 'non-Christians will not feel excluded' or so they will 'not feel offended' by Happy Christmas. If you feel offended by someone wishing you happiness at a time they are happy, then I think there is something seriously wrong with you. And if you can't join others in their celebrations, even if the theology behind it does not correspond with yours, then I think you lack mudita. As usual, the Buddha had something to say that is relevant to this issue. He said that the sage would happily participate in Brahminacal sacrificial festivals (yanna) and traditional family celebrations (yajanti anukulam sada) where nothing against the Precepts was involved (S.I,76).
I wish all my readers and Christian friends and their families a most happy and joyous Christmas.
