This is very useful in keeping up Brahmacharya. It makes you Oordhvaretas. The seminal energy is transmuted into spiritual energy, Ojas-Shakti. This is also called sex-sublimation. You will not have wet-dreams, Spermatorrhea. In an Oordhvareto-Yogi the seminal energy flows upwards into the brain for being stored up as spiritual force which is used for contemplative purposes (Dhyana). When you do this Asana, imagine that the seminal energy is being converted into Ojas and is passing along the spinal column into the brain for storage.
Sirshasana is really a blessing and a nectar. Words will fail to adequately describe its beneficial results and effects. In this Asana alone, the brain can draw plenty of Prana and blood. Memory increases admirably. Lawyers, occultists and thinkers will highly appreciate this Asana. This leads to natural Pranayama and Samadhi by itself. No other effort is necessary. If you watch the breath, you will notice it becoming finer and finer. In the beginning of practice there will be a slight difficulty in breathing. As you advance in practice, this vanishes entirely. You will find real pleasure and exhilaration of spirit in this Asana.
Great benefit is derived by sitting for meditation after Sirshasana. You can hear Anahata sound quite distinctly. Young, robust persons should perform this Asana. Householders who practise this should not have frequent sexual intercourse.
6. Sarvangasana (All-Members Pose)
This is a mysterious Asana which gives wonderful benefits. Spread a thick blanket on the floor and practise this Asana on the blanket. Lie on the back quite flat. Slowly raise the legs. Lift the trunk, hips, and legs quite vertically. Support the back with the two hands, one on either side. Rest the elbows on the ground. Press the chin against the chest (Jalandhara Bandha). Allow the back-shoulder portion and neck to touch the ground closely. Do not allow the body to shake or move to and fro. Keep the legs straight. When the Asana is over, bring the legs down very, very slowly with elegance and not with any jerks. In this Asana the whole weight of the body is thrown on the shoulders. You really stand on the shoulders with the help and support of the elbows. Concentrate on the Thyroid gland which lies on the front lower part of the neck. Retain the breath as long as you can do with comfort, and slowly exhale through the nose.
You can do this Asana twice daily, morning and evening. This should immediately be followed by Matsyasana (fish-posture). This will relieve pains in the back part of the neck and intensify the usefulness of Sarvangasana. Stand on the Asana for two minutes and gradually increase the period to half an hour.
This is a panacea, a cure-all, a sovereign specific for all diseases. It brightens the psychic faculties and awakens Kundalini Sakti, removes all sorts of diseases of intestine and stomach, and augments the mental power.
It supplies a large quantity of blood to the roots of spinal nerves. It is this Asana which centralises the blood in the spinal column and nourishes it beautifully. But for this Asana there is no scope for these nerve-roots to draw sufficient blood-supply. It keeps the spine quite elastic. Elasticity of the spine means everlasting youth. It stimulates you in your work. It prevents the spine from early ossification (hardening). So you will preserve and retain your youth for a long time. It helps a lot in maintaining Brahmacharya. Like Sirshasana, it makes you an Oordhvaretas. It checks wet-dreams effectively. It rejuvenates those who have lost their potency. It acts as a powerful blood-tonic and purifier. It tones the nerves and awakens Kundalini. Spinal column is rendered very soft and elastic. This Asana prevents the early ossification of the vertebral bones. Ossification is quick degeneration of bones. Old age manifests quickly on account of early ossification. The bones become hard and brittle in the degenerative process. He who practises Sarvangasana is very nimble, agile, full of energy. The muscles of the back are alternately contracted, relaxed and then pulled and stretched. Hence they draw a good supply of blood by these various movements and are well nourished. Various sorts of myalgia (muscular rheumatism), lumbago, sprain, neuralgia, etc., are cured by this Asana.
The vertebral column becomes as soft and elastic as rubber. It is twisted and rolled as it were like a piece of canvas sheet. A man who practises this Asana can never become lazy even a bit. He is a two-legged talking squirrel. The vertebral column is a very important structure. It supports the whole body. It contains the spinal cord, spinal nerve and sympathetic system. In Hatha Yoga the spine is termed as Meru Danda. Therefore you must keep it healthy, strong and elastic. The muscles of the abdomen, the rectic muscles and the muscles of the thigh are also toned and nourished well. Obesity or corpulence and habitual chronic constipation, Gulma, congestion and enlargement of the liver and spleen are cured by this Asana.
7. Matsyasana (Fish Posture)
This Asana will help one to float on water easily with Plavini Pranayama. Therefore it is called fish-pose, Matsyasana. Spread a blanket and sit on Padmasana by keeping the right foot over the left thigh and the left over right thigh. Then lie flat on the back. Hold the head by the two elbows. This is one variety.
Stretch the head back, so that the top of your head rests on the ground firmly on one side and the buttocks only on the other, thus making a bridge or an arch of the trunk. Place the hands on the thighs or catch the toes with the hands. You will have to give a good twisting to the back. This variety is more efficacious than the former one. The benefits that you derive from this variety are a hundred times more than what you get in the previous variety.
Those fatty persons with thick calves, who find it difficult to have Padmasana (foot-lock), may simply sit in the ordinary way and then practise this Asana. Practise the Padmasana first. Make it firm, easy and steady. Then take Matsyasana. Do this Asana for 10 seconds in the beginning and increase it to 10 minutes.
When you have finished the Asana, slowly release the head with the help of hands and get up. Then unlock the Padmasana.
You must practise this Asana soon after Sarvangasana. It will relieve stiffness of the neck and all crampy conditions of the cervical region caused by long practice of Sarvangasana. This gives natural massage or shampooing to the congested parts of the neck and shoulders. Further it affords the maximum benefits of Sarvangasana. It is a complimentary Asana of Sarvangasana. Rather it supplements Sarvangasana. As the larynx or wind-box and trachea (wind-pipe) are thrown open widely, this Asana helps deep breathing.
Matsyasana is the destroyer of many diseases. It removes constipation. It brings down the accumulated faecal matter to the rectum. It is useful in asthma, consumption, chronic bronchitis, etc., on account of the deep breathing.
