 Think about something and build that state. Build it bigger and bigger and bigger and have more control, more focus on how it affects the physical world. Even though our mind is outside the physical world, we can control the physical world because we do it every time we move our finger, right? Our mind is separate from our brain, yet how do we move our finger? So we just have to get used to the idea that our mind is more powerful than we give ourselves credit for.
