A: They have all the same capabilities of the Lizard beings except for the fact that their physical appearance is entirely different and they do not have souls of their own and also their biological structure is internally different. But, their functioning is the same and in order to remain as projection beings they also must absorb nutrients in the same fashion both spiritually and physically as the Lizard beings do. The reason the negative energy is necessary fuel is that the Lizard beings and the Grays are both living in the fourth level of density, which is the highest level of density one can exist in serving only self as these entities do. So, therefore, they must absorb negative energy because the fourth level of density is the highest example of self service which is a negative thought pattern.
The fourth level of density is a progression from the third level of density. With each progression upward in density level, the existence for the individual conscious entity becomes less difficult. So, therefore, the fourth level of density is less difficult to exist in that the third, the third is less difficult than the second and so on. It puts less strain on the soul energy. Therefore, beings existing on the fourth level of density can draw from beings existing on the third level of density in terms of absorption of negative soul energy. Likewise, beings on the third level of density can draw from beings on the second level of density, though this type of drawing is not as necessary but is done. This is why human beings existing on the third level frequently cause pain and suffering to those of the animal kingdom who exist on the second level of density because you are drawing negative soul energy as beings who primarily serve self, as you do, from those on the second level, and on the first, and so on. Now, as you advance to the fourth level of density which is coming up for you, you must now make a choice as to whether to progress to service to others or to remain at the level of service to self. This will be the decision which will take quite some time for you to adjust to.
This is what is referred to as the "thousand year period." This is the period as measured in your calendar terms that will determine whether or not you will advance to service to others or remain at the level of service to self. And those who are described as the Lizards have chosen to firmly lock themselves into service to self. And, since they are at the highest level of density where this is possible, they must continually draw large amounts of negative energy from those at the third level, second level, and so on, which is why they do what they do. This also explains why their race is dying, because they have not been able to learn for themselves how to remove themselves from this particular form of expression to that of service to others. And, since they have such, as you would measure it, a long period of time, remained at this level and, in fact, become firmly entrenched in it, and, in fact, have increased themselves in it, this is why they are dying and desperately trying to take as much energy from you as possible and also to recreate their race metabolically.
