The female experience
Tantric guru
In  the female body, the point of concentration is at Mooladhara chakra,  which is situated at the cervix, just behind the opening of the uterus.  This is the point where space and time unite and explode in the form of  an experience. That experience is known as orgasm in ordinary language,  but in the language of Tantra it is called an awakening. In order to  maintain the continuity of that experience, it is necessary for a  buildup of energy to take place at that particular Bindu or point.  Usually this does not happen, because the explosion of energy dissipates  throughout the body through the sexual medium. In order to avoid this,  the woman must be able to hold her mind in absolute concentration on  that particular point. For this, the practice is known as Sahajoli.
Actually, Sahajoli is concentration on the Bindu, but  this is very difficult. Therefore, the practice of Sahajoli, which is  the contraction of the vaginal as well as the uterine muscles, should be  practiced over a long period of time.
If girls  are taught Uddiyana bandha at an early age, they will perfect Sahajoli  quite naturally with time. Uddiyana bandha is always practiced with  external retention. It is important to be able to perform this in any  position. Usually it is practiced in Siddhayoni asana, but one should be  able to do it in Vajrasana or the crow posture as well. When you  practice Uddiyana Bandha, the other two Bandhas - Jalandhara and Moola  bandha occur spontaneously.
Years of this  practice will create a keen sense of concentration on the correct point  in the body. This concentration is more mental in nature, but at the  same time, since it is not possible to do it mentally, one has to start  from some physical point. If a woman is able to concentrate and maintain  the continuity of the experience, she can awaken her energy to a high  level.
According to Tantra, there are two  different areas of orgasm. One is in the nervous zone, which is the  common experience for most women, and the other is in Mooladhara chakra.  When Sahajoli is practiced during Maithuna (the act of sexual  union), Mooladhara chakra wakes up and the spiritual or tantric orgasm  takes place.
When the female yogi is able to  practice Sahajoli for say 5 to 15 minutes, she can retain the tantric  orgasm for the same period of time. By retaining this experience, the  flow of energy is reversed. Circulation of blood and  sympathetic/parasympathetic forces move upward. At this point, she  transcends normal consciousness and sees the light. That is how she  enters the deep state of Dhyana. Unless the woman is able to practice  Sahajoli, she will not be able to retain the impulses necessary for the  tantric orgasm, and consequently she will have the nervous orgasm, which  is short-lived and followed by dissatisfaction and exhaustion. This is  often the cause of a woman's hysteria and depression.
So, Sahajoli is an extremely important practice for  women. In Uddiyana, Nauli, Naukasana, Vajrasana and Siddha yoni asana,  Sahajoli comes naturally.
The practice of Amaroli  is also very important for married women. The word Amaroli means  'immortal' and by this practice one is freed of many diseases. The  practice of Amaroli over a prolonged period also produces an important  hormone known as prostaglandin which destroys the ova and prevents  conception.
 Tantric guru
Just as in the scheme of creation, Shakti is the  creator and Shiva the witness of the whole game, in Tantra the woman has  the status of guru and the man of disciple. The tantric tradition is  actually passed on from the woman to the man. In the tantric practice,  it is the woman who initiates.
It is only by her  power that the act of Maithuna takes place. All preliminaries are done  by her. She puts the mark on the man's forehead and tells him where to  meditate. In ordinary interaction, the man takes the aggressive role and  the woman participates. But in Tantra, they switch roles. The woman  becomes the operator and the man her medium. She has to be able to  arouse him. Then, at the right moment, she must create the Bindu so he  can practice Vajroli. If the man loses his Bindu, it means that the  woman has failed to carry out her functions properly.
In Tantra it is said that Shiva is incapable without  Shakti. Shakti is the priestess. Therefore, when Vama Marga is  practiced, the man must have an absolutely tantric attitude towards the  woman. He cannot behave with her as men generally do with other women.  Ordinarily, when a man looks at a woman he becomes passionate, but  during Maithuna he should not. He should see her as the divine mother,  Devi, and approach her with an attitude of devotion and surrender, not  with lust.
According to the tantric concept, women are more  endowed with spiritual qualities and it would be a wise thing if they  were allowed to assume higher positions in social affairs. Then there  would be greater beauty, compassion, love and understanding in all  spheres of life. What we are discussing here is not patriarchal society  versus matriarchal society, but Tantra, particularly left hand Tantra.In Tantra, the practice of Maithuna is said to be  the easiest way to awaken Sushumna, because it involves an act which  most people are already accustomed to. But, frankly speaking, very few  are prepared for this path. Ordinary sexual interaction is not Maithuna.  The physical act may be the same, but the background is totally  different.
In the relationship between husband  and wife, for example, there is dependency and ownership, but in Tantra  each partner is independent, one unto himself. Another difficult thing  in tantric Sadhana (spiritual practice) is cultivating the attitude of  passionlessness. The man has to virtually become Brahmacharya in order  to free the mind and emotions of sexual thoughts and passion which  normally arise in the presence of a woman.
Both  partners must be absolutely purified and controlled internally and  externally before they practice Maithuna. This is hard for the ordinary  person to comprehend because for most people, sexual interaction is the  result of passion and physical or emotional attraction, either for  progeny or pleasure. It is only when you are purified that these  instinctive urges are absent. This is why, according to tradition, the  path of Dakshina Marga (Dakshina marga is the right path of  yoga practices without sexual enactment.) must be followed  for many years before the path of Vama Marga (Varna marga  is the left path which combines sexual life with yoga practices in order  to explode the dormant energy centers.) can be entered.  Then the interaction of Maithuna does not take place for physical  gratification. The purpose is very clear - awakening of Sushumna,(  the middle pranic channel , it runs through the spinal cord)  raising the Kundalmi energy from Mooladhara chakra, and exploding the  unconscious areas of the brain.
If this is not  clear when you practice the Kriyas and Sushumna becomes active, you will  not be able to face the awakening. Your head will get hot and you will  not be able to control the passion and excitement, because you have not  tranquilized your brain.
Therefore, in my  opinion, only those who are adepts in yoga qualify for Vama Marga. This  path is not to be used indiscriminately as a pretext for  self-indulgence. It is meant for mature and serious minded householder  Sadhakas, who are evolved, who have been practicing Sadhana to awaken  the energy potential and to attain Samadhi. They must utilize this path  as a vehicle of awakening; otherwise it becomes a path of downfall.
