In your previous lifetime, you may have disappointed, betrayed, or hurt another before closing your heart to them. To open your heart, you may meet again this lifetime and re-experience the karma by switching roles to feel what it was like for them. If another has hurt you in this life, honour this is karma arising for you to learn something essential. Forgive it so you may live in your open heart. You have a huge heart, and you are ready to forgive and trust others again.
With all my love and blessings,
