Hindu's have you ever tried vipana mediation?

One think i would like to tell you sammatha meditaion helps you calmer yourself and attain sammadi and whereas vipana meditaion makes yourself know who you are and get out of your birth cycle.If you never try how does you know what is true at least try it oneself and then stick to your dogma if you have mastered it and nothing difference in your attitude it just seeing what is happening to you.
