Introspection is not special for Yom Kippur, for we judge every moment. We judge people every time we meet, judge situations at every moment, and mostly judge ourselves. But the criteria for our trial is quite questionable. The standards that we judge throughout the year are the product of the battering of consciousness. A product of mood, social norms, expectations, desires, prejudices, social conditioning and much more. All that unselected mass allows itself to judge everything in front of us as if the truth is in his hand.
On the other hand there is one day in the year in which we are supposed to disengage from those human standards, and be reflected according to Gods standards. Yom Kippur is a day which there is no eating or drinking, no action 'Sabbath of Sabbaths', and in fact there is no ordinary human existence. There is supposed to be only a divine consciousness that allows us to see reality according to Gods will.
Once a year we are supposed to cleanse our consciousness and examine ourselves in light of the ultimate truth. Once a year we are supposed to raise and see reality as it really is, without human judgment.
And this is the work of Yom Kippur, or the Jewish meditation I intend to do on this coming Yom Kippur.
