I do not know how you feel about it, but you were a female in your last earthly incarnation. You were born somewhere around the territory of Central Russia approximately on 1225. Your profession was chemist, alchemist, and poison manufacturer.
You were sane, practical person, materialist with no spiritual consciousness. Your simple wisdom helped the weak and the poor. Your lesson - to conquer jealousy and anger in yourself and then in those, who will select you as their guide. You should understand that these weaknesses are caused by fear and self-regret.
