Vipassana meditation as taught by S.N. Goenka. It's for free and you are able to learn this wonderful technique in 10 days.
This way of meditation helped me to stay present, remain aware and equanimous with reality as it is. Not as I would like it to be.
There is heard wisdom, intellectualized wisdom and experienced wisdom. The first two are very common. Only the third (i.e. right meditation practice) will be applicable in daily life.
For example: I knew anxiety is useless for me, damaging me. Still I wasn't able to stop it. By applying this technique to anxiety inducing situations I was able to calm down and see the anxiety pass away.
Everything arises and passes away.
