Do I Need To Concentrate On The Way I Sit During Meditation?

So my wife tells me that I need to sit straight doing meditation.

But as time goes by,

My body relaxes and it's not straight anymore.

Do I need to concentrate on the way I sit during meditation?

Or can I just focus on my breath?

The most important thing is to be aware of your breath.

But when your body is not in the right state,

That phenomenon usually occurs when you lose focus on your breath.

While you are focusing on your breath.

And if you realize that your body's position is not where it should be.

When you constrain yourself out,

Correct your posture while maintaining that focus on your breath.

So it's not a binary,

Right?

It's not a choice between straightening your posture or maintaining focus on your breath.

You should correct your posture while maintaining focus on your breath.
