Yes both. The first many years ago as evidenced by the condition of all of creation is my body. The answer to everything and all things is simple. Yet can not be expressed via the body or it's limited mind nor tongue nor can I long sustain this state as it dimineshes over hours numbering 12. Focusing and withdrawing all nervous energy & all body into the third eye center produces this after effect. When nothing exist but a single bright light in the darkness and an oceanic roar occures.
Now it is less mind blowing perhaps due to over 25 years of learning to integrate this incredible experience. I do get minor glimpses or openings of this experience after meditation. God bless my poor wife she sees the difference and is trying to understand it. The personality she knows is there yet not and I have to be careful not to just blurt things out and make her say how did you know that? How did you know I was thinking this thing or that. How did you know this thing or that happened or was going to?
The last time it happened was due to impatience and ego gratification as well as my spiritual immaturity and I apologized trying to explain Sorry after effect of meditation nothing special please pardon my rudeness.
Second the serpent coiled expressese its essence in varying degrees and strikes the centers as focused on bringing waves or ripples on calm water. Expressed to the inpure mind and body I posess as energy and tingeling and erections pardon my crudeness please yet the erectness of the lingam or penis while emiting fluid during meditation does lead towards lack of interest of both coitus or physical sex including self gratification as the thought becomes one of are you kidding me this is so unfulfilling compared to the ecstacies encountered while practicing my poor incomplete version of Kriya bereft of an incarnate Guru in the light of the beauty and ecstasy felt in the spine and its astral centers it is not only a poor shallow substitute but revealed in its animal nature and is a no thing. Reality is beautiful the crude physical plane is just a how can I say this a matt finish facsimile.
Yet never the blue sky looked so beautiful and blue nor the clouds so white and perfect nor the green of the tree so vibrant as when seen through the eyes in the after effect of my sadana.
Oh Lucky am I the witness . The I who perceives after true meditation.
In plain English release through the crude physical vessel not only falls short of the ecstacies to be experienced but the discharge acually diminishes the superior ecstacies to be found in the attempt to activate the astral centers via pranayama truncated Kriya Altered Kriya or not. This being stated I obviously believe in the theories concerning glands being effected by the centers from experience not book reading.
Why would anyone trade 1 ounce of physical gratification or gold for 100 ? Answer: No one would that knows the difference truly we worldly people are the true renunciants.
Later this bodily activation of the sex organs decreases and ceases to become a distraction as the energy largly due to the practice of navi Kriya calms this childishness down.
Until then dress appropriatly for ones sittings. As I understand it this is a minor example of Kundalini activation another example is the physical tongue becoming so enervated that it tries to push past the soft pallet into the nasal pharanax.
I have experienced this and the thin lingual frenulum actually twanged and there was a small tear. Be careful the physical can be overcame when meditating by the estatic flows encountered.
These are my experiences I may not be correct I have no Guru incarnate yet, so I am doing my best please do not take my writing as someone who knows I know that I know not and seek someone to awaken me.
