Is the harvest based upon this current incarnation or is it cumulative?

Harvest is not tied to any particular incarnation.

Thus the harvest is automatic in that those harvested will respond according to that which is unchangeable during harvest. That is the violet-ray emanation. However, these helpers are around to ensure a proper harvesting so that each entity may have the fullest opportunity to express its violet-ray selfhood.

Violet ray emission of the entity shows the entity's total progress in its journey, and is result of all its experiences and deeds up to that point, including that incarnation. Along with the coming harvesters, helpers ensure that the entity's violet ray emanation will be manifesting its full nature during harvest, despite conditions in its incarnation or the planet. This shows entity's real nature independent of the environment. Then the entity is slated for whatsoever location in existence is suitable for its existence after that point. This may not be the same planet or same density.

Spiritual biases are the strongest elements which determine the nature of an entity. They manifest and change over very long duration - lifetimes -, and they are not easily changeable within one single incarnation.

Thus, harvesters and helpers would not have huge difficulty in isolating the entity from its disadvantageous circumstances in its incarnation or making up for the factors affecting that entity and providing an environment in which the entity will fully manifest its violet ray.

Long story short, it doesnt depend on one incarnation. It doesnt depend on whether you are incarnated or not. All that is necessary seems to be being present in the energy field of the planetary sphere that is going through the harvest.
