Psychology = Leo is a Virtue & Principle of courage & Leadership; it’s ruled by the sun, and this gives you the energy of self-sense entitlement and the need to be on stage, which makes you want to be liked and get attention for your creativity & Talent. Also, this is your solar plexus, the primary vehicle that the “spirit” used to attract attention around you and protect your soft/Sensitive spot, aka your “Moon sign,” which is known as your Merkaba. Furthermore, the heart can be seen as the King of the jungle in your body since it must keep pumping blood around your body, delivering oxygen and nutrients to your cells/Self; that’s why Leo deals with being fixed or persistent.
Physiology = The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should. These 2 pathways pulmonary circulation is a short loop from the heart to the lungs and back again. Systemic circulation carries blood from the heart to all the other parts of the body and back again.
