You have everything you need for the extravagant journey that is your life. don juan
Life in itself is sufficient, self-explanatory and complete. Why then do men need to invent and re-invent gods and offer them their first born? For some covenant that gives all their descendants the promised land?
All my descendants shall inherit the earth, and the oceans. Why would I limit them to only one land? Especially one surrounded by concertina wire holding at bay the barbarian hordes who will stop at nothing to prevent a unique brand of DNA unlike their own in less than 1% of the strand?
What god would expect or accept such a sacrifice? One worthy of worship?
The creative universal force doesn't roll dice with the devil. Truth and beauty is available to all for the seeing, for the feeling, for the experience. No promises, no guarantees.
If you can't appreciate that, no amount of human sacrifice will change it.
