In the scriptures the function of the KHERUB assigned by God is to protect the Tree of Life and the entrance of the Paradise, both currently prohibit to mankind. Now a days the modern science has found numerous secrets without the increasingly closer relationship of illumination and knowledge, but it has not generated in the new scientists the acuity of conscience necessary to direct the investigations. In addition to the risks of physical nature always present on the occasion of an inconsiderate manipulation of the DNA or the unleash of considerable energies locked in the deep structure of matter, the effects of these manipulations on the researchers themselves and, on human populations as a whole, could reveal themselves very harmful even before being discovered by the precariously partial knowledge they have. Science demands a prudence which may be feared to be lacking who let themselves be dominated by the drunkenness of their illusory power. The consequences of these errors trying to manipulate the Tree of Life could allow the intervention of the Kherub.
