Three States of Semen
The vital energy or ‘Prana’ in a person basically exists in three states
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 actions 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 on his leg muscles. When a boxer is in the ring, his life force centers around his arm muscles. When a chess player is in the midst of a game, his life force is concentrated in his brain, and so on.
Gross state or semen state
When a man is under sexual excitement, his life force or Prana is withdrawn from every part of the body and focused into the sex center.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 for the basic energy required for his vital organs to function, has now come down to the sex center. Energy is in a state 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 due to all his Prana being 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 secrete 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.
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 the ‘Ojas State.’ The full power of this state is said to come to a Brahmachari after 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 world/astral planes. He can get astral visions and knowledge of creation and God. 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 hundreds of miles (Dooradristi), and many more.
