forms of semen

Hello there :-)

Trust you are doing good.
Coming to your query regarding the forms of semen, here is an elaboration:

The vital energy or ‘Prana’ in a person basically exists in three states.

1.   NORMAL STATE OR SUBTLE STATE: In the normal state, vital energy is spread over the entire body (in blood, bones, muscle, nerves etc…) giving us energy to indulge in various day to day activities. Pranic energy in this state is integral with the entire body in a state of harmony and union. The body is fully geared and in availability of life force to perform action efficiently. Based on the kind of activity we indulge in, life force flows to that particular part to perform the action. For example when an athlete gears up to run a marathon, his life force focuses into his leg muscles. When a boxer is in the ring, his life force centers around his arm muscles, when a chess player in midst of a game, his life force is concentrated in his brain and so on.

2.   GROSS STATE OR SEMEN STATE:
When man is under sexual excitement, his life force or Prana is withdrawn from every part of the body and focused into the sex center. Life energy which was earlier in a subtle state of amalgamation with his blood, flesh etc… in the NORMAL STATE, separates from those regions to a large extent and flows to his sex center. This sends a signal for his testes to produce sperm. The prostate gland gets ready with the prostatic fluid. The Cowper’s glands ready up the Bulbo Urethral fluid. Man is now fully geared up to engage in the sex act. Almost all his vital energy, except the basic energy required for his vital organs to function has now come down to the sex center. Energy is in a sate of wait to propel semen out of his system. Note how sexually aggressive a person becomes when he is fully aroused in the sex plane. This is further to all his Prana in a state of sexual focus. In this state man cannot efficiently indulge in any other activity other than the sexual act. Ask a fully aroused man to play a game of chess… he might not even remember the movements! Semen in this state is the linear, gross representation of his Prana or vital energy in liquid form. Energy which was earlier in electricity like form has now become physical, embodied in liquid semen.
In a man who constantly resides in the sex plane, his Prana is mostly in this gross semen form. This is the reason such people cannot effectively carry out any other form of work. The nature of gross semen is expellation. Its sole purpose is to reach outside to aid reproduction. This is called the ‘ejaculatory mode’. It cannot perform any other function in this state. If not let out immediately, it will flow out in a wet dream.
Once in the ‘ejaculatory mode’ semen can never be fully reconverted back to Pranic energy. The sexual glands secreted various physical secretions to manufacture gross semen. All these processes are not fully reversible even through transmutation and meditation. There are severe limitations. A considerable volume of vital energy will flow out, immaterial of meditation or celibacy, once it has reached this final gross form due to sexual duress.

3.   VERY SUBTLE STATE OR OJAS STATE:
When a yogi leads a life of true celibacy, conserving all his vital energy and transcending it from its NORMAL STATE to a highly concentrated, very subtle state through techniques such as meditation, asana, Pranayama etc… His Prana becomes very subtle in nature. Its intensity increases to a great extent. It is akin to gross water being heated and converted to superheated-gaseous steam in a distillation plant. Vital energy now has enormous potential energy. It rises up like steam does and reaches his ‘AJNA CHAKRA’ or the point between his eyebrows. This is called ‘OJAS STATE’. The full power of this state is said to come to a Brahmachari further to 12 years of true celibacy, without wastage of even a single drop of semen. His Pranic energy is now totally sublimated. It gives him the ability to enter the metaphysical word/ astral planes. He can get astral visions, knowledge of creation, god etc… Advanced Urdhvareta yogis get powers such as ‘Trikala Gnyana’ or knowledge of the past, present and future. Many ancient sages in this state had ‘Ashta Siddhis’ or eight superhuman powers like Levitation (ability to fly), astral travel, ability to make the body microscopic or macroscopic, ‘Bhuta vidya’ or the power to converse with wild animals and win their obedience, Listening to sounds many miles away (Doorashravana), Power of sight ranging to hundreds of miles (Dooradristi) and many more
(I will give a detailed description of all the Siddhis for the information of celibates in another answer sheet) Most importantly, the yogi gets vision of God and is blessed with self-realization. This is the highest state.

Celibates should understand what exactly sublimation is all about. Urdhvareta kriya in reality is not conversion of gross semen into Ojas. It is conversion of subtle/ normal Prana into Ojas, by preventing the formation of gross semen. If you continuously indulge in sexual activity that brings down Prana from its NORMAL STATE to a lower GROSS/SEMEN STATE, sublimation becomes difficult and roundabout. It must again be brought back to its NORMAL STATE and then taken to the VERY SUBTLE/ OJAS STATE.

The answer to what happens in a man at the start of celibacy lies in this fact. At the start of celibacy when man shuns sex stimuli, his Prana or vital energy comfortably rests in the NORMAL/SUBTLE state. Earlier it was being brought down to form semen. Now that need has been removed. The body stops production of earlier quantities of semen. Initial stages of celibacy do not really involve re-absorption. Most volume of semen in gross form at the start of celibacy actually flows out. It is due to lack of further production by which energy levels go up. This is exactly why for celibacy to bear fruit say beyond three months or so, sublimation into OJAS is necessary. Till this time the body is actually not in a state of re-absorption. It is only in a state of non-production and in a state of harmonization of existing Prana at the SUBTLE STATE. Further to this, production of gross semen goes on reducing and formation of more and more Prana goes on increasing (provided the celibacy is true and genuine)

So when we say sublimation of semen into higher forms, it is really sublimation of Prana in NORMAL STATE into OJAS STATE. For Prana to reach NORMAL STATE, man should desist from sexual excitement thereby prevent formation of GROSS/ SEMEN STATE. In an Urdhvareta yogi, this is fully achieved. His body does not produce gross semen at all. The vital energy required to sustain his body and intellect are fed from that part of his Prana. The rest is fully converted to OJAS.

Trust this makes things clear. Revert to me for clarifications if any.

God bless and have a nice day :-)
