Karmic difference between conciously withheld catalast and freely given catalyst

[Plenum]

I am particularly interested in waves of wanderers or other groups sent to provide the very difficult catalyst to others. For example incarnating in the position of a slave master, or maybe in the position of torturing another.

We take on forms and we take on energies of conflicting natures to our soul. What is there then to learn from hurting another in such a blatant way?

What is the beauty and where is the learning in such difficult positions? And why are some sent here with the responsibility to treat others so poorly?

well, it all depends on the kind of model you have for incarnation, and the kind of parameters that govern circumstances by which a certain life is chosen.  A negative entity would be looking for situations that would offer further opportunities to further their polarity:

A negatively oriented individual mind/body/spirit complex will ordinarily program for wealth, ease of existence, and the utmost opportunity for power. Thus many negative entities burst with the physical complex distortion you call health.

The issue is not that Earth needs more negativity or a**hole behaviour as you call it - this is a mixed polarity planet after all - there's going to be plenty enough of that catalyst.

And it's also the case that one doesn't need an abundance of so-called negative catalyst to grow fully - it is the element of Free Will and the Veil which provides the full rainbow and variety of catalyst for the self; not the presence of overt negativity.

My belief is that no matter how positive or negative the circumstance there is still growth or evolution of the spirit.

this is true.  But it's provided by the self, for the self.  I think you are looking too much at the external agent as a source of catalyst.

Everything is subject to interpretation by the self.
