It’s quite common for our mind to wander during meditation. The instruction when you notice this happens is to kindly direct your attention back to the focus of your attention.
Setting simple intentions before practice can serve as guiding lights for you to stay on your path (and kindly guide yourself back when you fall off.
For one pointed awareness our primary intention might be
”To direct attention to the Om, the breath, the body (whatever you’ve used as the object for meditation)”
The secondary intention could be
”If i notice my mind has wandered I will kindly and gentley guide it back to the breath”.
Just setting these intentions before practice primes your for focus and kind guidance.
