The Light aspect:

Ruling Planet: Venus which rules Taurus (Feminine) and Libra (Masculine).  Venus represents the Goddess of love.    

Anahata:  The Heart Lotus.

Element: Air.  

Aspect: Balance.  

Friday:  Friday is the day of the week for this chakra. 

The Shadow Aspect:

The shadow aspects of the heart chakra is weakness and having a victim mentality and being too dependent on others.  The heart chakra shadow can be balanced by letting go of the martyr not letting people walk all over you. 

 I have included a Heart Chakra meditation video.
