How to count Pranayamas? (Kriya Yoga)

[hoherbasti]

Hey there everyone, I was wondering how you all count your pranayamas (108 long breaths where you chant ohm between the eyebrows).

My problem is, that I can't keep my focus on the point between my eyebrows whilest counting (even with a mala chain or finger counting).

Is there maybe a way or some advice for counting to 108 whilest fully concentrating on the ohms and your breath (= whilest moving neighter body or mind)

Even some kind of gadget, necklace or wristband that automatically counts your breaths and beeps at a certain number would be great.

 

 

Have a nice day everyone
