According to some religious and spiritual traditions, the practitioner attempts to blank her or his mind. Thought is viewed as an obstacle to genuine understanding. It is not using the mind that is the problem - but misusing it. As I understand this statement, it means that one should always keep in mind the spiritual reality of all things. True meditation enables us to recognize this cosmic Unity as it is seen in all things.
Meditation is an essential part of human nature.
All of us meditate. From my POV, meditation from a Baha'i perspective means to focus on the verities in the revealed words of God and their authorized interpretations.
