🧠 Inside You: The Builders, the Waste, and the Roads

Table of contents

In Ayurveda, understanding health isn't just about knowing what's wrong — it's about truly knowing your body. If you've followed our "Know Your Body" series, you've already met the three doshas (Vata, Pitta, and Kapha) and learned how disease develops through six predictable stages.
Now, let’s go deeper into the body. Ayurveda teaches that our body is built, maintained, cleansed, and sustained by three main systems:
🔹 Dhatus — the building blocks
🔹 Malas — the body’s natural waste
🔹 Srotas — the body’s transport network
These three form the physical foundation of life. Let's explore each one.
🧱 1. Dhatus – The Seven Builders of Your Body
Think of your body as a building. What materials are used? Bricks, cement, wood? In Ayurveda, your body is made and maintained by seven tissues known as dhatus.
Each dhatu has a unique role and is nourished in a step-by-step manner. Like an assembly line, each tissue supports the next.
Sanskrit Name | Modern Reference | Main Function |
Rasa | Plasma/Nutritive fluid | Nourishes all tissues, supports immunity |
Rakta | Blood | Carries oxygen, energizes, gives colour |
Mamsa | Muscle tissue | Provides strength, support, and movement |
Meda | Fat | Lubricates, cushions, stores energy |
Asthi | Bones | Gives structure and firmness |
Majja | Marrow/Nervous system | Supports brain, nerves, and immunity |
Shukra/Artava | Reproductive tissue | Fertility, creativity, vitality |
When you eat well and your Agni (digestive fire) is strong, these tissues form properly.
But when digestion weakens, tissues may not develop completely, leading to immature, dysfunctional dhatu.
➡️ This leads to the formation of Ama — more on that below.
🚽 2. Mala – The Waste That Must Leave the Body
Just as every kitchen or factory generates waste, so does your body — and this is not a sign of disease, but a part of healthy metabolism. These waste materials are called Malas.
The three main malas are:
Mala | What It Is | Function |
Mutra | Urine | Removes liquid waste, salts, and toxins |
Purisha | Stool | Eliminates the waste portion of properly digested food |
Sveda | Sweat | Removes minor toxins and helps regulate temperature |
✅ Important clarification:
Ayurveda doesn't say that stool is made of undigested food.
Purisha is the separated waste part of fully digested food — what the body doesn’t absorb.
If these malas aren’t eliminated properly, they can stagnate and disturb doshas.
However, Ama is not the same as stagnant mala — and that brings us to the next concept.
🔬 Understanding Ama – Not a Toxin, But a Sign of Immature Metabolism
In popular writing, ama is sometimes loosely translated as "toxin," but Ayurvedically, it is much more specific and deeper.
Ama is the result of poor transformation, due to weak digestion (Agni) — either at the stomach level (Jatharagni) or tissue level (Dhatvagni).
It represents a hypo-functional or immature state — for example:
When Rakta Dhatu is improperly formed, immature red blood cells (like reticulocytes) enter circulation.
When Meda Dhatu is poorly transformed, sticky fat may accumulate, leading to sluggish metabolism.
Ama clogs the body’s systems, weakens immunity, and acts as a seed for future disease. It’s not just undigested food — it’s a sign that the body isn’t processing and transforming nutrients correctly.
🕸️ 3. Srotas – The Body’s Transport Channels
Your body has an elaborate network of srotas — subtle channels that carry air, food, blood, waste, thoughts, and even hormones. They are the roads, pipes, and cables of the body.
There are 13 main srotas (plus many subtypes). A few examples:
Srotas Name | Carries | Function |
Annavaha Srotas | Food | From stomach to intestines |
Pranavaha Srotas | Breath / Prana | Life energy and oxygen distribution |
Raktavaha Srotas | Blood | Circulates blood to nourish tissues |
Mutravaha Srotas | Urine | Liquid waste removal |
Svedavaha Srotas | Sweat | Controls body temperature, detox |
When srotas get:
Blocked (Sanga)
Overflowing (Atipravritti)
Going the wrong way (Vimarga gamana)
…it leads to disease conditions.
Ama, when formed, often lodges in these srotas and causes blockages — which is why Ayurveda focuses so much on cleansing therapies and diet.
🔄 How It All Works Together
Let’s now connect everything into one Ayurvedic flow:
You eat food → Jatharagni digests it
Nourishment flows via srotas to build dhatus
The waste part becomes malas like urine and stool
If Agni is weak, transformation is poor → leading to Ama
Ama clogs srotas, dhatus suffer, and disease begins
So, good health means good transformation and flow, not just absence of disease.
🌿 How to Keep Your Dhatu, Mala, and Srotas Healthy
Here are a few simple Ayurvedic lifestyle habits you can start today:
✅ Eat warm, fresh, home-cooked meals (supports Agni)
✅ Sip warm water throughout the day
✅ Do gentle movement daily (opens srotas)
✅ Never hold back natural urges (mala balance)
✅ Oil massage (Abhyanga) once a week
✅ Sleep on time — this is when dhatus regenerate
Final Thoughts
Your body is more than what you see in the mirror. It’s a living system of creation, nourishment, elimination, and flow.
Dhatus build and support you
Malas keep you clean and light
Srotas ensure everything reaches the right place
Agni powers it all
And Ama shows us where healing must begin
By understanding these layers, you’re not just learning Ayurveda — you’re learning to live in tune with your nature.
