From the Hebrew Old Testament comes the meaning of the name Barack...

H1288
בּרך bârak
baw-rak'
A primitive root; to kneel; by implication to bless God (as an act of adoration), and (vice-versa) man (as a benefit); also (by euphemism) to curse (God or the king, as treason)...
Strong's Dictionary

And interesting thing about the Hebrew use of this word is that it certainly has the primary meaning of pronouncing a positive blessing...however it can also be used as the above Strong's dictionary points out as a euphemism for a curse. That's just the way Hebrew works.

For every benefit there is the potential to abuse the benefit to great detriment. One of the abuses of בּרך bârak is to use the power of blessing for one's own benefit rather than the benefit of others. This in fact is very descriptive of a great deal of "christian" religion in this day. I will address more on this later...this is enough for now to ponder.
