Blessed are the poor in spirit

First sister Lily says this to me, and then I got one of those Christian emails yesterday & it was again on 'the poor in spirit'.

I googled it and Catholic Encyclopaedia says,
The word poor seems to represent an Aramaic 'ányâ (Hebrew 'anî), bent down, afflicted, miserable, poor; while meek is rather a synonym from the same root, 'ánwan (Hebrew 'ánaw), bending oneself down, humble, meek, gentle. Some scholars would attach to the former word also the sense of humility; others think of "beggars before God" humbly acknowledging their need of Divine help. But the opposition of "rich" (Luke 6:24) points especially to the common and obvious meaning, which, however, ought not to be confined to economical need and distress, but may comprehend the whole of the painful condition of the poor: their low estate, their social dependence, their defenceless exposure to injustice from the rich and the mighty. Besides the Lord's blessing, the promise of the heavenly kingdom is not bestowed on the actual external condition of such poverty. The blessed ones are the poor "in spirit", who by their free will are ready to bear for God's sake this painful and humble condition, even though at present they be actually rich and happy; while on the other hand, the really poor man may fall short of this poverty "in spirit".

So it's an attitude you adopt, where you lean heavily on God for your needs.
