It sounds like you may be misunderstanding what meditation is. Meditation is to observe what is happening in your body and mind. There isn’t really a “topic” other than what comes up in your mind. But you aren’t supposed to linger on your thoughts, only notice their arrival and passing.
You can choose to focus your attention on specific things such as your breathing, sounds, the feeling of a location of your self, etc. Is that what you mean by topic?
Write a “meditations” on whatever
