The seven dhātus are like the layers of a temple, each one more refined, more sacred and essential to sustaining life and vitality.
What Are the Dhātus?
In Ayurveda, the Saptadhātu (seven dhātus) are the seven tissues that make up the human body.
The Sanskrit word Dhātu comes from the root Dhā, meaning to hold or support — these are the very substances that hold the body together.
As Aaron explains in the podcast:
“The dhātus give us our form, our nourishment, our strength, and ultimately our vitality. They’re what hold everything together within the body.”
Just as a temple is built layer by layer until it’s refined enough to hold divinity, our bodies are nourished through successive layers of refinement.
Each tissue depends on the nourishment of the previous one, transforming food into vitality, structure, and consciousness.
The Story of the Temple
To illustrate this, Aaron shares a story:
“Once upon a time, there was a builder who constructed a temple. Each day, he laid foundations, placed bricks, shaped timber, copper, silver and finally gold until the temple was refined enough to house divinity.”
In the same way, the body is built through seven stages of refinement, each dhātu transforming nourishment into the next until the final product becomes Ojas, the essence of vitality and immunity.
How the Dhātus Work
Paige describes the dhātus as a supply chain of nourishment:
“Each tissue takes what it needs from the digested food, then passes on what’s left to the next tissue. Every layer becomes more refined until, eventually, Ojas is formed.”
This process takes around 35 to 40 days from the moment you eat.
That means the food you eat today nourishes you over the next six weeks.
The Seven Dhātus Explained
1. Rasa Dhātu – Plasma & Lymph
Function: Nourishment and circulation.
Dosha: Kapha.
Upadhātu (Secondary Tissue): Breast milk and menstrual fluid.
Mala (Waste Product): Mucus and Kapha secretions.
Supports: Warm, light, sweet foods like dates, ghee and soups. Abhyanga (oil massage) enhances lymphatic flow.
“Rasa is the first layer of nourishment - like sap in a tree, it flows through the body, hydrating and sustaining all other tissues.” – Paige
Balanced Rasa brings hydration, sweetness and emotional connection. Imbalanced Rasa shows up as lethargy, congestion or lack of appetite.
2. Rakta Dhātu – Blood
Function: Circulation, vitality, warmth.
Dosha: Pitta.
Upadhātu: Blood vessels.
Mala: Bile.
Supports: Iron-rich foods like beetroots, carrots, legumes and leafy greens. Exercise or sauna to get the blood pumping.
“When there’s blood moving through your body, there’s warmth, strength and nourishment. Everything is fed through the blood.” – Aaron
3. Māṃsa Dhātu – Muscle
Function: Strength and structure.
Dosha: Kapha (Earth element).
Upadhātu: Ligaments and skin.
Mala: Earwax and mucus.
Supports: Protein-rich foods — legumes, grains, nuts, eggs and high-quality dairy.
Yoga practices that create resistance (e.g., Chaturanga or long-held āsanas) build both strength and stability.
“Quality of food equals quality of tissue. You can have lots of tissue but poor quality. Nourishment builds strong muscles.” – Paige
4. Meda Dhātu – Fat Tissue
Function: Lubrication, protection, insulation.
Dosha: Kapha.
Upadhātu: Omentum and organ fat.
Mala: Sweat.
Supports: Healthy fats like avocado, ghee, nuts, and seeds. Balanced rest and gentle exercise (like yoga or sauna) regulate fat metabolism and reduce stress-related weight retention.
“Fat gives us a sense of safety and stability — it’s the body’s coat, protecting us from the outside world.” – Paige
5. Asthi Dhātu – Bone
Function: Structure and support.
Dosha: Vāta (Air element).
Upadhātu: Teeth.
Mala: Hair and nails.
Supports: Calcium-rich foods like sesame seeds, legumes, grains, and seaweed. Weight-bearing activities (walking, yoga, gentle impact) help strengthen bones.
“The bones give us our physical structure — without them, we’d be a meat suit on the ground.” – Aaron
6. Majjā Dhātu – Bone Marrow & Nerve Tissue
Function: Communication, nerve conduction, immunity.
Dosha: Kapha.
Upadhātu: Whites of the eyes.
Mala: Eye secretions and tears.
Supports: Grounding foods — soups, stews, nuts, seeds and oils. To create demand, practice restorative yoga, meditation, and deep rest — less is more for nourishing the nervous system.
“Majjā is the nervous system — the gooey inside that allows communication and response throughout the body.” – Paige
7. Śukra Dhātu – Reproductive Tissue
Function: Reproduction, regeneration, creativity.
Dosha: Kapha.
Upadhātu: None (considered pure).
Supports: Sweet, nourishing foods like dates, ghee, honey, and milk. Practices like Mūla Bandha, pelvic awareness, and gentle apāna vāyu work strengthen and balance reproductive health.
“Śukra is the essence of all previous tissues — it’s not just about reproduction, but creativity, vitality, and deep energy.” – Aaron
Why the Dhātus Matter
Paige sums it up beautifully:
“Each tissue needs something different. We have to eat good-quality food and digest it well — because every tissue relies on what comes before it.”
When the dhātus are nourished, Ojas — the vital essence of immunity and spiritual strength — naturally arises.
