Can you tell if someone is in love with you?Or has a crush on you by doing this?:

As you evolve, it becomes easier to sense the person's aura and feelings and even to see them, especially if you're a natural empath. There's a meditation on reading the person's thoughts in ToZ, it's in the intermediate stage of advancement, and there I've been able to feel the energy of many people. It's possible, but it depends on your progress in the meditations, how open you are, etc.
