Sattvic people are possessed of love, faith, devotion, honesty and truthfulness. Tantra works to maximise a being's mental energy which then balances and harmonises the body and spirit. These elements make up the body, are present in every cell. These individual cells are not able to live independently of the whole body. Similarly we are all cells in the Universal Organism and are not able to live independently of the whole.
Earth is a solid state of matter whose characteristics are stability, fixity and rigidity.
It creates a feeling of groundedness and security in the individual. It is a stable substance. Water is the liquid state of matter which has a flowing, dissolving, carrying and cleansing quality. It is a substance without stability. Fire has the ability to transform solids to liquids to gas and vice versa.
