a lot of people live in an emotional prison without realizing. The experiences and Karma we either live through or inherit create an emotional prison because we don't want to experience these same experiences again and so we try to avoid any kind of situation which our unconscious matches with a past trauma.
So a lot of people go through life making the same decisions over and over again because they are afraid to relive that experience. But that just makes us live in a shoebox... Spiritual growth is about letting go of old emotions and getting rid of old Karma... There are many possibilities to do that one of them is intense yoga and advaita vedanta. Also i help in releasing old emotions.
another possiblity are Bija Mantras. I recorded some on Youtube
