What does polarization mean? Are there 3 polarities?

[Infinite]

Okay, fine, but this doesn't describe what polarity looks like, smells like, tastes like. 

I believe this explain EXACTLY what polarity is:

You may look at each mind, body, spirit complex within the third-density illusion as a source of energy—energies that are expended either in service to others or in service to self. If you could look at the metaphysical nature of the metaphysical expenditure of energies by each entity, this would provide you with a measure, shall we say, of the efficiency of the energy expenditures, even into the areas of the quantification of percentages. The entity who is able to express 51% of its energies by intention in its life pattern, then will find itself available for the harvest in the positive sense.

The entity who expends 95% of its energies in directing that love quality to the self, will similarly find itself in the opportunity to be harvested in the negative sense, for the negative entity will find it is much more necessary to be consciously aware of each expenditure of energy, for it is much more difficult to contact intelligent infinity using the lower chakras, red through yellow, leaving out the green and making contact with intelligent infinity by communicating through the blue chakra and the indigo. Thus the requirement for the negatively oriented entity is somewhat higher, shall we say, for it travels the path of that which is not, the path of separation. This is a viable path to the one Creator but requires a greater degree of accuracy in the expenditure of energy.

I always saw the polarity as the direction in which the energy is used (this includes thoughts, emotions and deeds). But, this energy is enough to express a polarity only if the prana is flowing without blockages (for this reason is necessary open the green-ray chakra to become harvesteable to STO fourth-density).
