The contribution from the mother in creating the fetus is called Matruj Bhav. The Charak Samhita links it primarily to the formation of the baby's delicate and soft organs.

Organs like the heart, navel, skin, fat, blood, flesh, bladder, pelvis, liver, spleen, pancreas, kidneys, intestines, and rectum are associated with Matruj Bhav.

The mother's egg contributes half of the baby's DNA. During pregnancy, the mother's body, uterus, and placenta provide the necessary nutrition and a safe environment for development.

The father's contribution to the formation of the fetus is called Pitruj Bhav. The Charak Samhita connects it mainly to the baby's stable and strong structures.

Hair, teeth, nails, facial hair, bones, veins, muscles, arteries, and certain traits linked to fertility are included in Pitruj Bhav.

The father's sperm also contributes half of the baby's DNA. Therefore, both mother and father have equal biological importance in creating the child.

Based on Charak's spiritual perspective, the aspect related to the soul entering the womb is Atmaj Bhav. This is not derived from the parents; it is linked to the soul's own journey, past impressions (Samskaras), and unique consciousness.

Knowledge, mind, senses, life force (Prana), inspiration, retention, voice, complexion, the experience of joy and sorrow, desire, patience, intellect, ego, consciousness, memory, and lifespan are associated with Atmaj Bhav.

Even siblings from the same parents can differ vastly in nature, preferences, and abilities. Every child has their own unique identity.

Diet, habits, and lifestyle that have become agreeable to the body and mind are called Satmya in Ayurveda. The foundation derived from this is Satmyaj Bhav.

Qualities like good health, enthusiasm, sensory wellness, fertility, a cheerful disposition, and a healthy complexion are linked to Satmyaj Bhav.

This concept aligns with lifestyle, physical adaptability, and surrounding environment. Diet, sleep, exercise, stress, and other environmental factors can influence the mother's health and impact the baby's physical development (Epigenetics).

In Ayurveda, the nutrient essence derived from digested food is called Ras. The nourishment the fetus gets from this essence is Rasaj Bhav.

The formation of the body, growth, satisfaction, nourishment, and enthusiasm are associated with Rasaj Bhav.

Nutrients from the mother's diet reach the baby through the placenta and umbilical cord, fueling their growth.

The foundation connected to the mind and psychological tendencies is called Satvaj Bhav. According to Charak, these traits manifest in varying proportions in every individual.

Mental traits such as devotion, attachment, purity, anger, drowsiness, irritability, gentleness, seriousness, restlessness, sacrifice, bravery, fear, aggression, and jealousy are linked to Satvaj Bhav.

A baby's temperament isn't shaped by a single thought or event. It is a combination of genetics, brain development, innate nature, and the future family environment. A calm and supportive environment during pregnancy is crucial for the mother's mental well-being.
