As long as you are a beginner certain formalised meditations, or prayers may be good for you.
But for a seeker for reality there is only one meditation - the rigorous refusal to harbour thoughts. To be free from thoughts is itself meditation.
You begin by letting thoughts flow and watching them. The very observation slows down the mind till it stops altogether.
Once the mind is quiet, keep it quiet. Don't get bored with peace, be in it, go deeper into it.
