One needs to learn soul consciousness and god consciousness to enter in the Meditation stage.
Soul consciousness is firmly determining oneself as bright shining star like soul, an entity distinct from the body and abandoning the body consciousness. In the beginning, it takes some time to practice.
God Consciousness - God or Supreme Soul who is the enternal source of all powers and during meditation, the inflow of the qualities - divine virtues, light and might to the soul takes place.
