Hi there A Silver 8.The Heart Chakra is about Love, Kindness and Affection. When it is open, you are compassionate and friendly, and you work at harmonious relationships.When your Heart Chakra is under-active, you are cold and distant.If the Heart Chakra is over-active, you are suffocating people with your Love and your Love probably has quite selfish reasons embedded within it.In regards to doing the Golden Altar Exercise and Forgiveness and Release this means that you have had alot of Furstration, Anger, Hurt and Pain locked up in that area of your Auric Fields and in your Mind Patterns.By doing the Golden Altar Exercise it means you are able to Forgive and Release but this also alters the Negative Emotions attached to your Heart Chakra so it is simply a sensation of exposing the Pain and Hurt manifested around your Heart Chakra.I hope this helps A Silver 8.Take care my friend.
