Somehow as a child we created an attitude towards life as a reaction to painful circumstances. As a child you weren’t able to understand everything that happened and to deal with it the reaction is to shield off the pain and find ways to get round it. Once such a way to try to ignore the pain starts all next experience will count to that. It is like starting to wear coloured glasses. Once your glasses are yellow you see the world as yellow and everything in the world IS yellow to you.
A shaman is an expert in feeling and especially in feeling these deeper layers that we try to shield off and ignore. By embracing that deeply felt pain which is unconscious the pain becomes transformed and is no longer there. This way your attitude towards life becomes transformed and life will respond to that.
