what does it mean when your chakra gets clogged at your heart...I really can only get a little flowing thorugh

All that that really means is that your heart chakra has never really been cleansed propperly. It also means that there are past expirences and actions that have built up over time.

Easiest way for a beginer to cleanse there chakras is to hand your self over to a higher power once just to give you a clean slate to work from.

This is a meditation from doreen virtue that goes like such.

Lie down and clear you mind.
Call upon an archange gabriel or raphael can do this perfectly.
Ask the angel to enter your body to fluch out all the toxic energy dwelling there.
You will sense a being enter your body and then exit taking all the dark away
After wards further meditaions you sould take up would be general chakra clensing and energy development
