You would have heard about the seven chakras (energy centers); it is One Energy that manifests itself in various forms.
In the first chakra (Muladhara), at the base of the spine, the energy manifests as enthusiasm or inertia.
When the same life force energy comes to the second chakra (Swadhisthana), it manifests as sexual energy or creative or procreative energy.
The same energy goes up to the navel region, the third chakra (Manipura), and manifests in four different forms, which relate to four different emotions – greed, jealousy, generosity and joy. That is why all these four emotions are depicted through the tummy.
Jealousy is an emotion that one feels in the stomach. Generosity is depicted with a large tummy, e.g., Santa Claus. Joy is also depicted with a big tummy, e.g., Lord Ganesha and the Laughing Buddha.
The same emotion comes to the fourth chakra (Anahata), the heart chakra; manifests as three different emotions which are love, hatred and fear.
When this energy rises to the fifth chakra (Vishuddha), at the level of the throat, it symbolizes grief and gratefulness. When you feel grief, the throat chokes, and when you feel grateful also, the throat chokes.
The same energy then goes in between the eyebrows to the sixth chakra (Ajna), and manifests as anger and alertness. Anger, alertness, knowledge, and wisdom are all related to the third eye centre.
The same energy goes to the seventh chakra (Sahasrara), at the top of the head and manifests as sheer bliss. That is why in any sanctuary experiences, when you feel total bliss, the mind immediately goes to the top of the head. Something shoots up to the top of the head and you feel blissful.
So, the upward movement and downward movements of energy are all the emotions in life.
