Why is it not free

The answer to this question is simple:

It is not free because it is my job and I am like you, with various and varied tasks in my daily life.

At the moment, the universe doesn't pay my bills and I don't eat prana, so I need financial compensation like everyone else.

Would you work for free? I don't think—

It must remain fluid and just in the energies between the giver and the receiver, it is one of the universal laws of the Universe.

(I specify that in case of need, I practice however gratuitousness on a case by case basis.)
