When you just sit, naturally, some thought will arise in you. See from where the thought is rising or which part of the body experiences movement or feeling through that thought.
You will see, one by one, each thought creates some sensation in some internal organ in your body. Try to see which thought is connected to which sensation happening inside your body. Try to locate the internal organ feeling the sensation, the organ that produced the thought coming into your mind. Do this with each thought.
When you experiment with this technique, if it clicks for you within twenty-four hours, this is the technique for you. If not, continue to try other techniques. This is a technique that can directly give you the enlightenment experience.
