Wherever or whenever you practice, take it easy like playing.
Someone might say, “I am very busy. I do not have time to practice” or “I cannot do it, I am not pure enough.” These are excuses.
If we intend to do something, we can find time to do it. Whatever we do, be aware. For example, if you are a teacher, when you pick up a pen, pick it up with awareness. While you are writing, be aware.
This is the natural way of cultivating self-awareness, learning Dhamma with nature.
