We talk a lot about the importance of healthy digestion, and that improper digestion can have a negative effect on health. In addition to the fact that when food is digested improperly it can lead to the formation of toxins called ama that are precursors to disease, improper digestion also prevents the tissues of our body from being properly formed. Ayurveda calls these tissues dhatus.
“Dhatu means tissue. The seven dhatus are the seven types of tissue that make up the human body. Since Ayurveda considers both a physical and a subtle body, the seven dhatus make up both of these bodies. The seven dhatus are rasa, rakta, mamsa, medas, asthi, majja and shukra.
The health of the seven dhatus is paramount to the health of a person. When the seven dhatus are functioning normally, they allow the body to express the will of the ego and/or the soul. Pathology of the dhatus results in either an excess or deficiency of tissue. This results in symptoms.
Dhatus are passive tissues in the sense that they respond to the state of the doshas. Doshas, when out of balance, are the causative agent of disease. A dhatu becomes either deficient or excessive when a dosha invades the tissue. Hence, it could be stated that the dhatu is the site of the disease and the dosha is the cause.
When vata enters a tissue, the tissue becomes lighter. Hence, it becomes deficient. When kapha enters a tissue, the tissue becomes heavier and hence excessive. When pitta enters a tissue, the tissue becomes overheated and burns up. In the long term, this results in a lightening of the tissue and deficiency. However, in the short term it simply heats the tissue and causes inflammation.”
And ~ there is actually an eighth tissue element, called ojas. “Ojas is really not a tissue and hence it is not considered a dhatu. Rather it is the essence that gives the tissues strength and endurance. It is the force that keeps the tissues healthy. Ojas is the stabilizing force of the body and mind. It allows the body and mind to resist stress and disease. It protects the body against faulty impressions taken in through the five senses.”
How to ensure healthy dhatu and ojas formation? It always comes down to digestion. Eat proper foods, properly. The importance of this cannot be overstated! We have posted numerous times about ways to ensure healthy digestion. Exercise also aids in digestion, as does the cultivation of a calm mind. Yoga and Ayurveda teach that the best way to achieve peace of mind is through meditation.
With a calm mind and healthy digestion, you’re well on your way to a healthy body and mind, free of disease!
