As we discussed in our previous article (Beyond the Red Myths), various menstrual taboos are practiced across cultures worldwide. While they often seem superstitious on the surface, most of them follow two core principles:

1. Anulomana Theory

2. Pheromone Theory

In this article, we will focus on the Anulomana Theory and its connection to both Ayurveda and modern scientific principles.

Anulomana Theory

The term “Anulomana” is derived from Sanskrit, meaning downward flow. According to Ayurveda, all movement or flow in the body—whether physical, chemical, or subtle—is governed by Vata (Vayu). Without Vata, no flow can occur, or the flow may move opposite to its natural direction.

Essentially, the kinetic energy of the body is governed by Vata. During the bleeding phase of menstruation, the body helps eliminate waste by maintaining Anulomana flow, which is the natural downward movement of energy and matter.

Understanding this concept allows us to make sense of many menstrual taboos: wherever natural flow is hampered, the activity is often restricted. Let’s explore some examples.

1. Entering Water Bodies (Swimming, Rivers, etc.)

• Hydrostatic Pressure: When the body is submerged in water, it experiences hydrostatic pressure—the pressure exerted by the weight of water surrounding the body.

• Venous Return: This pressure pushes blood from the limbs toward the chest, increasing central blood volume.

• Impact on Anulomana Flow: Since blood is being pulled upward, the natural downward flow of Vata is hampered, requiring additional energy to maintain equilibrium.

2. Excessive Exertion

   During menstruation, excessive exercise or exertion can lead to Vata vruddhi (increase in Vata).

   Increased Vata may interfere with the natural downward movement, hampering the Anulomana flow. This can manifest as irregular flow, cramps, or other discomforts.

Hence, Ayurveda recommends light activity or rest during this phase to maintain natural downward energy flow.

3. Use of Menstrual Cups

• The principle of Anulomana emphasizes letting blood exit naturally without interruption.

• Menstrual cups may block or hold the flow, interfering with the body’s natural elimination process.

• Preferred Option: Sanitary napkins, which allow the blood to flow freely while maintaining hygiene.

4. Temple Entry Restrictions

• Vastu Shastra: The ancient Indian science of architecture that designs buildings to channel cosmic energy.

• Garbha Gṛha: The innermost sanctum where the deity resides. Typically:

  • Under a pyramid-shaped structure to focus energy from above (Phys.org, 2018).

  • Above a copper plate (Tamra Patra) to conduct energy (Ajantahc.com).

The combination of pyramid structure and copper base

• The soles of the feet directly contact the stone floor, which is connected to Earth.

• The human body is an electrical system (nervous system, heart impulses, cellular communication).

• Walking barefoot, especially near the Garbha Gṛha, allows the body to absorb subtle electrical and geomagnetic charges, which rise through the Nāḍīs (energy channels), balancing Prāṇa and calming the mind.

Humorously, this is “exactly good for us”—but not during menstruation. Why? Because it hampers the natural Anulomana flow when the downward energy is already in process.

5. Avoidance of Sexual Activity

• Sexual activity is generally discouraged during menstruation in Ayurveda.

• Why? Because the male reproductive organ moves energy upward, which is opposite to the natural downward flow of Vata during the bleeding phase.

• Maintaining Anulomana flow during this time prevents disturbances in both physical and subtle energies.

What Happens When Natural Flow Is Obstructed?

• Trapped energy: Instead of exiting, the energy is redirected, disturbing other doshas and channels.

• Potential consequences: Cramps, mood swings, menstrual irregularities, and even future reproductive issues.

Law of Conservation of Energy

• Principle: Energy cannot be created or destroyed; it only transforms from one form to another.

• Application to Natural Flow: If energy is obstructed:

  1. Accumulate: Energy builds up behind the obstruction, increasing potential energy.

  2. Redirect: Energy finds an alternate path, which may have unintended consequences.

  3. Release Suddenly: If the obstruction fails, energy is released rapidly, sometimes destructively.

Humorously, one could say: if downward energy (blood and Vata) is blocked, it transforms into pain—though this is not yet scientifically proven, it might be the future!

Maintaining the downward flow of energy is really important to prevent future reproductive issues. Here’s a simple, practical way you can try it yourself:

Dysmenorrhea, or period cramps, often happens when the Anulomana flow is obstructed. Drinking warm water starting five days before your period and continuing throughout can help—Ayurveda mentions that warm water supports the natural downward flow of energy, or Anulomana, easing discomfort naturally.

Conclusion

• Obstruction or redirection of this flow can lead to discomfort and potential long-term reproductive issues.

• Thus, following rajahswala paricharya is best.
