Dealing with angriness or sadness that comes up with "meditation"

It seems that you feel that you've been dealt with a raw deal in this life.

Accept who you are, what you've got and remind yourself the countless blessing you've got in this life and shun those negative thoughts.

Start with the first blessing which is you are born human..

concentrate on what I am doing

Concentration on what you do on its own right is not Insight Meditation. You have to be mindful of the arising and passing of sensations.

An acrobat, surgeon, ballerina, etc. must be concentrate on what they do, but this concentration does not make them less stressful. perhaps it makes them more stressful. This is what you are experiencing.

concentrate on my breath

This is very good. But when doing this release the tension in you body and mind by passing your mind in any areas there might be discomfort.

On emotional instability

Emotional instability is an offshoot of ill-will. In the case of being emotional equanimity.

I read your question, and I think my opinion is that the Buddhist belief system is not exactly "awareness that we are living in illusion", and it is not like a "similar belief in Hinduism" ... but Buddhism actually has wisdom and practices to help with sorrow and anger (in fact, "to help with sorrow and anger" is virtually the main purpose of Buddhism, i.e. the reason why the Buddha invented it) and so to answer your question I want to write a summary to introduce or explain Buddhism.

The Buddhists' "Noble Eightfold Path" has three partitions

• Virtue
• Mindfulness
• Wisdom

Any one of these can be helpful (and people are encouraged to make progress in all three):

• I think that "virtue" improves your relationship with yourself and other people, and can be helpful no matter what you think of karma.

• And "mindfulness" is to do with meditation, concentration, and insight.

• The basis of wisdom is the four noble truths, which are, something like,

  1. Suffering exists
  2. The origin of suffering is craving and ignorance
  3. Suffering ceases with the cessation of craving
  4. The Eightfold Path is the way which leads to the end of suffering

I expect that both "virtue" and "mindfulness" can help with sadness (for example, one of the suttas says that "skillful virtues" leads to "freedom from remorse", which leads to "joy", etc.).

I want to say a bit about "wisdom", how knowledge of the four noble truths might help with sadness:

1. "I am feel sad now: that's not surprising because things are well known to be unsatisfactory"
2. "If I feel sad that is because I am craving something"
3. "If I stop my ignorant craving then I will stop feeling sad"

In summary if I feel sad, then I recognize that I'm feeling sad; remember that sadness is associated with craving; wonder what craving is causing sadness; see that craving is or was ignorant (ignorant because it causes suffering); and intend for that craving to cease, and for the sadness which it originated to cease with it.

Another fundamental of Buddhist wisdom is that things are impermanent. If you're not feeling sad, and suddenly you feel sad, then maybe soon you'll feel not sad again (the sadness being impermanent).

As for dealing with "anger", the doctrine about three poisons suggest that anger is related to aversion ("I don't want that") which is again related to a type craving ("I want that not to be"); so anger too can be handled by non-craving ... or by advesa and metta.

If I sometimes (hopefully briefly) feel angry there's a verse I like to remember from the Dhammapada,

Hatred is never appeased by hatred in this world. By non-hatred alone is hatred appeased. This is a law eternal.

Well, I hope the above can be a useful introduction to Buddhism.

I didn't mention karma. I suspect that karma may be more important in Hinduism than in Buddhism, because apparently (correct me if I'm wrong) Hindus believe that our current state is caused by past karma (which is why you might be wondering about actions in a past life), whereas Buddhism believes that karma is only one of the factors which affects our current state.

I don't know what to tell you about your individual state. I'm not a doctor or a teacher.

For physical exercise I personally like bicycling more than jogging. I can cycle for hours (can't jog for hours), and find the exercise increases my breathing (more than walking does, e.g. because I try to cycle fast or up-hill) and it's relatively easy on my knees and hips etc.

One answer like this can't solve your problem (perhaps only you can solve your problem) but I hope you discover how to maintain equanimity.
