Be precise. What room? Where is the seat or cushion? What materials do you need? Which direction are you facing?
You need a place to return to again and again. It doesn't need to be the perfect place but it needs to be somewhere clear in your mind. It might be your bedroom, a spare room, your basement or living room. It doesn't matter where it is, so much that you know where to go when it is time to practice.
You need a place to start. A place you can commit to.
With time you can include more places and new places. The park, the beach, during your commute. Integration happens once you have something to integrate. First, you need a place to start. A place you can develop trust in yourself and cultivate a willingness to show up for yourself.
No one needs to know where you sit, but you need to know.
