Mantras and sound have been an integral part of yogic and spiritual disciplines for millennia. In prenatal yoga, the use of sound, vibration, and chanting can provide special advantages to the pregnant woman as well as the developing fetus within her womb. This chapter discusses the relevance, science, and use of mantras and sound in prenatal yoga, with an emphasis on how these resources can increase emotional balance, relaxation, and spiritual connection during pregnancy.
Sound is not just heard—it’s also felt. Each cell in the body is sensitive to vibration, and through pregnancy, the woman’s body is particularly attuned. Resonance generated by chanting mantras can extend through bodily fluids, tissues, and nervous system to the baby and create a profound sensory connection.
Scientific research on prenatal development has revealed that unborn infants react to sound from the 20th week of pregnancy. Continuous exposure to calming sounds like the mother’s voice or soft chants can have a beneficial effect on fetal growth, calm the baby’s nervous system, and promote bonding.
Mantras are sacred syllables, sounds, or phrases chanted in meditation or while practicing asanas. Mantras may be chanted out loud (vachika japa), whispered (upamsu japa), or mentally repeated (manasika japa). In Sanskrit, “man” is mind and “tra” is tool or vehicle—so mantra is literally “a tool for the mind.”
Mantras assist in grounding the mind, soothing erratic emotions, and calling upon a greater sense of spiritual consciousness. During pregnancy, when hormonal and emotional changes are typical, mantras serve as a stabilizing agent.
Repetitive chanting engages the parasympathetic nervous system, reducing cortisol levels and causing the mother to relax more profoundly.
The infant experiences the soothing vibrations, which can support emotional well-being and mental growth.
Chanting mantras like “Om” improves the flow of prana (life energy), which is crucial for a healthy pregnancy.
Rhythmic chanting or humming during childbirth can assist in pain control, provide steady breathing, and ground the mind during contractions.
The original sound representing creation, Om quiets the nervous system and synchronizes body, mind, and breath.
Translating to “I am That,” this mantra unites the practitioner to cosmic consciousness. It is usually linked with the breath—breathing in “So,” breathing out “Hum.”
A peace prayer, recited to call in harmony in body, mind, and surroundings.
A strong mantra from the Rigveda which calls for divine light. Should be employed only if one is already familiar and at ease with it.
Seed sounds that stimulate various chakras and assist pregnant women in keeping energetic balance.
Sound may be incorporated within various asanas during prenatal practice. Some of the following are a few examples:
Significance: Opens hips and enhances blood flow to the pelvic region.
Sound Practice: Chant “Om” or hum on exhalation to enhance relaxation.
Modification: Sit on a folded blanket or cushion to raise hips and support lower back.
Significance: Suits mantra chanting and awareness of breath.
Sound Practice: Recite “So Hum” silently or out loud with breath.
Modification: Place knees on blocks or cushions.
Significance: Favors digestion and tranquil mind.
Sound Practice: Utilize “Om Shanti” for grounding.
Modification: Support with a cushion between hips and heels.
Significance: Establishes stability and posture awareness.
Sound Practice: Breathe deeply in and exhale with a gentle humming sound to sense the vibration in chest and abdomen.
Modification: Do near a wall for support of balance.
Significance: Deeply restorative, especially post-asana and pranayama practice.
Sound Practice: Play soothing mantra music or silently repeat a mantra.
Modification: Place cushions under knees and behind the head for optimal relaxation.
Always make sure the mother is comfortable with sound practices. Some might be more at ease with silent repetition than vocal chanting.
Begin with simple mantras and short timing—3 to 5 minutes—and extend gradually.
Ask students to apply mantras that speak to them spiritually or emotionally.
Play recorded mantra music during restorative poses or meditation but not loud or complicated songs.
Mantras can be silently repeated while experiencing discomfort or episodes of anxiety for emotional control.
The use of mantras and sound in prenatal yoga is not just some cultural or religious tradition—it’s a wholistic means of fostering the mind, soothing the body, and bonding with the unborn baby. Repeated over and over, the vibration of mantras has the power to become an incredibly deep source of comfort, empowerment, and preperation for the life-altering process of childbirth. It is something that yoga instructors can encourage their students to investigate and find which sounds strike deepest during pregnancy.
