I had an interesting question today, so I thought I'd share the answer:
Ques: twice after meditation I found myself very angry and I
tried to express it in a safe way but did bite my husband's head off. Any thoughts on the matter. (from Judy in New Zealand)
S.S. ans: Yes, I do have very definite thoughts on the matter.
Anger seems to be a VERY common reaction to meditation. People are usually confused by it, as you expect medtation to make you more peaceful and hence, less angry.
Meditation works to purify your mind. We all have thoughts that we don't want to have - emotions that we don't want to express, etc. No yogi wants to be an angry person. So, in the past, when this type of thought started to form, we suppressed it - much like sweeping dirt under the carpet. But, meditation is like an intense spring cleaning - you pick up the carpets and give them a good shake. All of the hidden 'dirt" come out. I think it is a necessary part of the purification process. However, it doesn't mean that you're supposed to bite your husband's head off - learn to witness your own thoughts (and emotions) in a detached manner. Observe the negative thoughts, but do not act on them.
Yoga Sutra, verse 1.12 abhyasa-vairagyabhyam tan
"vrittis may be controlled by abhyasa (regular steady practice) and vairagya (detachment)".
