I’m not sure I see Olivia’s post but thank you for this question! Simply put - we are not trained for it. To hear our hearts, we have to quiet the mind, especially the aspects of the mind that are trying to protect us from danger. Scientifically, this is called Coherence. On a spiritual level, awakening our heart is what we are here on Earth to do. This is what the Upanishads point to as well. It’s hard to listen to our heart because listening to our hearts is what we’re in this Earth-school to practice!
