what spiritual aspects lead to fertility?

Fertility is the bond of life to cultivate itself. To preserve and generate the experience, the perception that has been collected through the ages. When we think of fertility, we cannot think of sexuality. In fact, there are three dimensions to fertility. The physical or sexual, the biological or reproductive, and the spiritual or evolutionary. To understand nature first it is compulsory to know the secret of the three Gunas in ayurveda. Reproductive biology is the information center through which the physical body is constantly remade from the information transmitted by the parents. In Ayurveda, this mechanism is likened together with the principles of Agni and Soma.

The woman reproductive element denotes the Agni Tattva and the male reproductive element represents the Soma Tattva. Ironically enough, the male personality represents Agni Tattva, whereas the woman personality represents Soma Tattva. In other words, the Agni Tattva is present in a seed form in the woman with a dominant Soma personality and the Soma Tattva is present in a seed form in the male with a dominant Agni personality.  Life manifests when Agni and Soma coalesce together in a delicate act of balance. Agni kindles the fire of metamorphosis and Soma serves as the gauntlet as well as the substance that undergoes metamorphosis expressing life. The heat from the Sun represents Agni Tattva and the waters of the Earth represent the Soma Tattva.  In Ayurveda, reproductive biology is the process through which the male and woman exchange the most refined expressions of Agni and Soma Tattva to recreate a new life.  This analogy is also the central theme of witchcraft in Ayurveda, which is known as Rasaśāstra. Rasa is the life fluid. Rasaśāstra is the fashion of creating life fluid from inert matter. Or transubstantiating inert matter into a form that can be accepted by the life fluid or Rasa. Mercury and sulphur form the base of this alchemical metamorphosis of inert matter, with mercury representing the semen of Lord Śiva and sulphur the menstrual fluid of Goddess Pārvati. Lord Śiva is the ultimate ascetic, an incarnation of the goods of Rasāyana, ever established in the state of expanded knowledge. Yet, he also represents perfect masculinity, the chastity of the reproductive element. Goddess Pārvati has to make extreme sweats to manifest the masculinity of Lord Śiva to produce a  get who's able of annihilating demoniac beings in the world.  Fornication triggers the medium of the exchange of the Agni Tattva and Soma Tattva to recreate life. therefore, a major function of fornication is to propagate reproductive biology. But in humans, fornication also serves an advanced function.  As bandied, the Agni Tattva is present in a seed form in the woman and the Soma Tattva is present in a seed form in the joker. The coming together of the male and woman personalities can potentially nurture the development and complete incarnation of the Agni and Soma Tattvas that are dormant in the female and male. The Agni dominant personality of the joker can inflame the awakening of the Agni Tattva that's dormant and in a seed form in the woman. Likewise, the Soma dominant personality of the woman can awaken the Soma Tattva that's dormant and in a seed form in the joker.  The woman's ovum and the ovulation cycle are in sync with the waxing and waning of the moon, strengthening the idea of the association with the Soma Tattva. The sexual element in the process of reduplication can open up the two individuals to protest and start this process of inner metamorphosis. A balancing of the Agni Soma Tattvas at the position of the personality of the individual prepares the person for a deep spiritual metamorphosis.  In Ayurveda, both the cranium and the uterus are compared to the conch. The Sanskrit word for conch is Śaṅkha, which means auspicious( śaṃ) space(Kha). The uterus is the auspicious space where the Agni and Soma Tattvas unite to produce new life, fulfilling the thing of natural reduplication.  The cranium is the auspicious space where the Agni and Soma Tattvas unite to complete the process of sickie-spiritual elaboration, which is possible if the male and female share in this process with mindfulness.  This conception is symbolized by the operation of the saffron and sandal pastes on the forepart by the male and female. After marriage, the woman applies the saffron grease paint on the forepart in an upward direction. This symbolizes the implicit awakening of the Agni Tattva in the woman under the influence of the man's personality. The man applies the sandal paste in the upward direction on the forepart symbolizing the implicit awakening of the Soma Tattva in the male under the influence of the female personality. Children who grow under the care of parents who are transubstantiating at the internal position by collective nurturing of the Agni and Soma Tattvas come well-predicated and inflame their spiritual elaboration.  Preparation for gestation and parturition  Ayurveda gives elaborate guidelines for generality,  gestation,  parturition, and neonatal care. Before generality, the quality of the Śukra (manly reproductive element) and Ārtava (woman reproductive element) is to be assessed and if necessary, treatment rules are to be administered.  Throughout gestation, both the nutrition and internal disposition of the mama need to be taken care of strictly to nurture the balanced growth of both the body and mind of the growing fetus. According to Ayurveda, kārmic engineering of the fetus can be done during the period of gestation. The growing fetus can respond to external stimulants and indeed learn while in the womb of mama. Ayurvedic textbooks state that mortal trouble( puruṣakāra) can abate the impact of daiva (goods of once deeds) if necessary interventions are made during the intrauterine life.  Therefore the authority for gestation,  parturition, and neonatal care in Ayurveda is aimed at the overall development of the new life with a specific emphasis on laying the foundations for spiritual elaboration at a  veritably early stage of life.
