Is kundalini awakening a requisit to Harvest?

[Infinite]

However, if one opens the violet center (potentiated intelligent infinity), or even taps into the 8th level (unpotentiated intelligent infinity)

The question 48.10 seems indicate that open violet center or taps 8th level is the same thing:

48.10 Questioner: Could you tell me how the various bodies, red through violet, are linked to the energy center, centers, red through violet? Are they linked in some way?

Ra: I am Ra. This shall be the last full query of this working.

As we have noted, each of the true-color densities has the seven energy centers and each entity contains all this in potentiation. The activation, while in yellow ray, of violet-ray intelligent infinity is a passport to the next octave of experience. There are adepts who have penetrated many, many of the energy centers and several of the true colors. This must be done with utmost care while in the physical body for as we noted when speaking of the dangers of linking red/orange/yellow circuitry with true-color blue circuitry the potential for disarrangement of the mind/body/spirit complex is great. However, the entity who penetrates intelligent infinity is basically capable of walking the universe with unfettered tread.

And I found a stretch from Latwii:

When the entity has sufficiently cleared each of the energy centers within the physical vehicle, then it is possible for the entity to reach from indigo ray through violet to the eighth energy level, and contact those portions of the one  infinite Creator known as intelligent energy and intelligent infinity, the latter producing the experience of unspeakable joy as the entity knows the full presence of the one infinite Creator.

Looks like the intelligent infinity is the eight energy level, so contact the intelligent infinity is contact the eight level. Where you found about a distinction?
