Rebirth Confrontation
A yogi will have difficulty with challenges for rebirth once he leaves the physical body.
This applies to yoginis as well.
Everyone who does not master the process of rebirth resistance before the physical form becomes inaccessible, will have difficult with the challenges for rebirth and will more than likely be circumstantially drawn into the formation of another embryo hereafter.
At a certain stage of advancement, one will find that during meditation, one is assailed repeatedly with sexual forms, especially sexual forms of females who will appear in the meditation at the third eye or at the buddhi analytical orb. One will see vague outlines of semi-transparent female forms, highlighting or being focused on their lower torso and thighs.
When this happens repeatedly during meditation, it will be very subtle and almost transparent, hence the yogin (yogini) will have to be very sensitive in psychic perception to even realize that this occurs.
Some students are unfortunate because they have no such experiences. They feel they are superior to those yogis who do, or they feel that yogis should not have pornographic or sexual explicit or nude visions. They feel that a yogi should be above that and if he or she has that, then it is an indication of deviation or upset, or laxness or inordinate sexual attraction.
Who is to say that a yogi or yogini who does not have such vision actually has these visions but just cannot perceive them due to lack of psychic sensitivity and lack of psychic perception?
These appearances of female, mostly females whom the yogi will not recognize, is a preview of what will happen hereafter to break down the resolve for resistance to rebirth. Sometimes the yogi will find that his (her) psyche is under the female which appears or is superimposed into the female and especially into the reproduction apparatus of that astral being.
In a way this is wonderful because it give the yogi some idea of what will happen hereafter if he failed to pass beyond certain astral domains just after he is deprived of the physical body.
