This is a quote from Chogyam Trumpa’s book The Myth of Freedom.
The usual problem is that, when emotions arise, we feel that we are being challenged by them, that they will overwhelm our self-existence or the credentials of our existence. However, if we become the embodiment of hatred or passion, then we do not have any personal credentials anymore. Usually that is why we react against the emotions, because we feel we might be taken over by them, that we might freak out, lose our heads. We are afraid of aggression or depressor will become so overwhelming that we might lose our ability to function normally, that we will forget how to brush our teeth or dial the telephone.
There is fear that emotion will become too much, that we might fall into it and lose our dignity, our role as humans beings. Transmutation involves going through such fear. Let yourself be in the emotion, go through it, give in to it, and experience it. You begin to go toward the emotion, rather than just experiencing the emotion develop. Then the most powerful energies become absolutely workable rather than taking you over, because there is nothing to take over if you are not putting up any resistance. Whenever there is no resistance, a sense of rhythm occurs. The music and the dance take place at the same time. That is the lions roar. Whatever occurs in the samsaric mind is regarded as the path; everything is workable. It is the fearless proclamation-the lions roar.
The lions roar is fearlessness in the sense that every situation in life is workable. Nothing is rejected as bad or grasped as good. But everything we experience in our life situation, any type of emotion is workable. We can see quite clearly that trying to apply the reference pointof credentials is useless. We have to really work into the situation completely and thoroughly. The basic point of lions roar is that we are able to deal with emotions directly.
