Hello,
Walking meditation is well established, one method is to repeat the words, 'Bodhisattva Mahasattva'. With each step, Bo-dhi-sat-tva Ma-ha-sat-tva. This is a Mahayana Buddhist practice.
Or you can count to 21 with each step, and then count backwards from 21. This method can also be used in our sitting practice.
It's important not to judge your practice, in doing this we take the long-term view.
Let the breath remain natural and relax, and relax again!
Dissolve into each breath and let go, and let be..........
Try meditation for 5 mins a day, no judgement.
