Some people travel to other dimensions in their astral bodies when they meditate.

Put on the music, and listen. Zazen means to sit, to listen. You're listening to enlightenment, to the universes, to the planes of mind.

Have your life properly aligned with dharma. The technicalities of the movement of the kundalini are easy to master. Dharma is much more complex.

To meditate what you need to do is free yourself from your ideas and your thoughts. All of the higher dimensional planes, the higher realities, the infinite cosmos itself is beyond thought.

To be in thousands of states of mind simultaneously as you perform simple physical tasks gives you a reverence for life. Each of these outer manifestations of life is God.

You'll notice all around the Hindu temples couples, statues and drawings, in various erotic forms of love-making. This used to give the British a lot of trouble because they were kind of white and uptight. It didn't quite fit. How could a temple of God be covered with pictures of people, in their term, fornicating?

Don't run away from the world. The world is God. Don't run towards the world. God is the void. Don't be afraid of the complexities of this life, nor the stark simplicity of death.
