There are seven chakras or seven nerve/energy centers connected with different glands in the body — thyroid gland, the adrenalin glands, pituitary gland, pineal gland, etc. Science also agrees that these glands are responsible for our experiencing various emotions. Our ancient Rishis knew this fact thousands of years ago and mentioned it in the scriptures.
The Rishis depicted each of the seven chakras in the forms of a lotus or different flowers. This is because when you go deeper in meditation, the consciousness becomes very subtle, and your mind becomes fresh like a flower. It becomes fresh, alive and soft. In such a delicate state of consciousness, you experience the rise of energy in the system.
Lightness is connected with subtlety. Grossness is connected with inertia and negative sensations; negative feelings. When you are negative, when you are rude or rough in your behavior, there is a certain inertia, a certain heaviness in the system.
When you feel all the positive sensations, you feel a sense of lightness. When the energy moves upwards, then the inertia transforms into enthusiasm and then next to creativity. From creativity wells up joy. When you are happy, you are naturally generous. Then the energy moves up further into the heart chakra where you only feel love for everybody around you. When you feel immense love, you feel an equal amount of gratitude and from this gratitude stems awareness. Awareness leads you to bliss.
