Far as im concerned you go for all or nothin. I read a quote once, enlightenment should be the focuse of one, for all other things will snag your progress. In essence all these things come during the process of becoming enlightened.
I tried developing these sort of mental abilitys once, it was crap.
Threw my many studys, and many different areas practised, the best i would say IS energy development. For in this everything els comes.
That below is a short description of the process, now this will give you Much more energy enough to break out in waves of vibrations that bring bliss. also a semi super consiouse state of mind. I say semi becouse i only used the righ nerve the first time. A super intuitional state can be attained threw uniting the left and right spinal nerves in the head, when done right a high pitch bird chirping noise will be generated. I always imagined 2 thin wires rubbing together really fast, like a grasshopper type ah deal. My dad oddly has this naturally, haha hes not spiritually inclined though, So he drinks. Hes also 40, age has nothing to do with nothin.
I remained in this higher state for about 2 months, but becouse it was all done with a one pointed type of intuition, i didnt know exactly how i was doing it, in thus i reversed my flow, and dicharged all my energy, ive taked the last 4 months to learn it, ive got the breathe energy down, and have just learned exactly how the fire was being made, all thats left is to re establish the circulation my friends (=.
I will mention a little. We loos Massive amounts of energy threw discharging sexual fluids. sorry, i dont know the full operations of a women yet as im ah guy. As i was saying, origanally befor we ever dicharge any fluid, semon is clear, as we do it more and more it becomes white, not to mention everytime we do it, the fluid is dicharged with enough energy to creat life. We loos life/energy threw the door of sex, and in this it is threw the door of sex we can gain energy and life.
The backwards flowing method it the first process, making the flow of energy that creates sexual energy reverse. This is done threw the circulation of light,also called the lesser heavenly cycle. This method can be done threw learning to breathe up the back, and down the front.
when using this techniqe, the yogic full breath can be incorporated, as it seems to be another way of unconciously creating the circulation. I had an extremly strong downwards flow, all my energy turned into sexual energy, in this everything was wasted, i did the circulation "constantly" turned it into my normal breathing for 2 or 3 months. in that time, i had reversed the flow of energy, i had no desier for sex for their was no enegy their, and i had a hard time getting horny the circulation was so strong.
Now, when the circulation is that strong, one can concentrate, and make your self horny, in a more techniqual mannor this is creating subtle energy, witch instead of staying in the sexual organs, goes up the back, as does the heat that is generated. This heat is a major key, it is the fire used to subliminate the fluid.
NOW the second part of the process is turning the fluids clear agian. Now i believe the circulation MAY do this on its own, but i Always incorporated breathe energy with it. Breathe energy can be aquierd threw using yogic pranayama techniques. its liike creating a suction in the diaphram, on both inhailation and exhailation. The body will vibrate, when you sneez, the tingle, or chill,vibration, this is the same subtle energy generated threw breathing. NOw you do the breathing technique, generate sexual fluids, must relax while doing this, abd be prude, always do it in prudence for its NOT about sex. Close the anus, this draws the fluid back, and focuse up wards, you will feel the fuid dissapear. this must be done untill fluids are clear, your armpit smell will also start to change, it gets better n better. after fluids is purifyd, you do everything the same, except with the fire, for the fire puts it into the body, if that is done right, the body will turn red. Befor all this can be done, even if the flow is reversed, one must keep circulating untill the left and right spinal nerves rise on the spine, hopfully to the ears.
When the spinal nerves rise youll know, as it may have to break threw the throat, in this itl sorta hurt, but you must relax and let it go threw, for itl be better after. mmm the tone in the head gets louder too. Happy days everyone.
