"Let the mind be still"

I tried this twice. And I dozed off both times. What am I doing wrong?

This is very common, PetroApocaplypse. Maybe you are tired?

If not tired, then falling asleep is also common when you close your eyes to visualize or meditate.

To solve this you can sit on a chair (wooden chair, or any chair that is not soft), or, if you can, sit on the floor with your legs crossed. If that is uncomfortable, sit on the floor on a firm pillow, or two, or three so that you are comfortable.

Then you can set a gentle alarm for just a few minutes. Maybe 3 minutes to begin. Then, over time, as is comfortable for you, gradually increase the amount of time you are sitting. Eventually, with practice, you will be able to sit like this for a half an hour, then even an hour.

Don't worry about thoughts that come up in your mind. If you notice them, acknowledge them... "Hello, thought." And then, let them go away as you redirect your mind to stillness, focus on your breathe only. Breathe in, breathe out naturally. When you focus on your breathe again, the thoughts will go away all by themselves. No controlling required here.

The mind is like a thousand screaming monkeys at first, when you begin this practice. I think of them as funny monkeys, then I go back to focusing on my breath. They go away. But they will quickly return at first

With all the benefits of quiet and stillness, and you won't fall asleep.
