Is blue chakra the wisdom chakra?

[Infinite]

I think that’s an important point for STO: Wisdom must be built upon a foundation of Love, lest it be cold and calculating. Negative entities form an earlier attachment to Wisdom. A purely wisdom perspective sees compassion as folly and unnecessary.

Yes. I noticed that the best way is balacing each chakra in the natural order.

First, the balance of the three lower centers which are the bases of the physical experience. I belive that is the hardest part of the seek.

So, the opening and balance of heart chakra and the achieving of the harvestability state. This is the most important work of third density, which can't be achived without the minimal balance of the three lowers centers.

The opening and balance of the blue-ray or throat chakra is easy to the entity with the heart opened (Ra said that). So, I believe you are right when said that love and light are aspects of the same thing. For this reason the STS path negate the green and blue rays.

In the indigo-ray center or the brow chakra, we have the creation of the adept. When this center is balanced contact with the inteligent infinity is made. The entity resurrect and becomes a new being. This state is called in some hindus sources of savikalpa samadhi which is like see God but still with duality (I and God).

Beyond indigo, in the end of the circuit of chakras, is the crown chakra or violet-ray center and when the kundalini raise to this center the entity can achived the Buddha's state. The veil is lifted and the entity become One with the Creator. This is called nirvikalpa samadhi in some hindu sources. Different from savikalpa samadhi, here all duality is dissolved and true unity with the One is achieved. It's yet described a state called sahaja samadhi in which there is constant nirvikalpa samadhi even when the entity is doing your daily activities. Perhaps Buddha's state would be the last samadhi, but the important is the conquest of the nirvikalpa samadhi, which I believe is the penetration into intelligent infinity.
