If you don’t get to chant or do anapana, what will happen?
We chant or watch the breath to purify the mind; however, wisdom must be present because anything you do without wisdom, the mind gets attached to the object. (We need to know why we’re doing it and with what attitude.)
If there’s attachment to any object, when you cannot get the object, then the mind gets upset. That’s the nature of attachment. Whatever you do repeatedly with delusion, you get attached to it.
Even with anapana, if you do it without wisdom, over a long time, you become attached to watching the breath.
Whatever you do, you need to know why you’re doing it – what benefits do you get from doing it? When wisdom is involved, then the activity is beneficial. (For example, we watch the breath or chant to calm the mind and to learn.)
