The word that was used for this was "Vipassana", which means "to observe reality in a special way", to observe it as it is - not just as it appears to be, not just as it seems to be, not coloured by any belief or philosophy, not coloured by any imagination - but to observe it by working in a scientific way.

For example, when anger has arisen, you observe the reality that anger has arisen. Cutting yourself off from the external object of anger, you simply observe anger as anger, hatred as hatred; or passion as passion, ego as ego. You observe any impurity that has arisen on the mind. You simply observe it, observe it objectively, without identifying yourself with that particular negativity.

It is very difficult to observe objectively. When anger arises, it is like a volcanic eruption, and we get overpowered by it.

When we are overpowered by anger, we cannot observe anger. Instead, we perform all the vocal and physical actions which we did not want to perform. And then we keep repenting: "I should not have done this. I should not have reacted in this way." But the next time a similar situation occurs, we will react in the same way, because we have not experienced the truth within ourselves.

If you learn this technique of observing reality within yourself, then you will notice that, as anger arises in the mind, two things start happening simultaneously at the physical level.

At a gross level - at the level of your breath - you will notice that, as soon as anger, hatred, ill will, passion, ego, or any impurity arises in the mind, your breath loses its normality. It cannot be normal. It will become abnormal - slightly hard, slightly fast.
