In Eastern and Middle Eastern cultures, mainly in the Chinese, Japanese and Hindu empires, the elements earth, water, fire, wood, and metal are the basis of natural balance. Each one influences the other positively or negatively the 5 elements. Also, in these cultures, it is discovered as the vital energy flows in the body of the human being.
The Chinese define it as lines of energy that flow through the body and pass through different organs. Each of them is identified with a natural element so that if we stimulate any point of a meridian, we will obtain the increase or decrease of energy in the organs of the body. This maintains a natural balance.
And the Hindu culture tells us that the chakras are spherical vortices (whirlpools) in the etheric body that act as energy transmitters. They influence our activity on the physical plane through the functioning of the endocrine glands (glands of internal secretion such as the thyroid). These glands affect our bodily functioning, mental balance, and emotional integrity. Depending on our use of them and our energies, they will be constructive or discordant.
