A cluttered mind is restless and unfocused.
Yoga teaches us to accept our personal limits, our individual states of mind and body.
In order to understand what clutter is, you need to define where it comes from.
Yoga is not about judging others. It is a practice of love. And it is just that—practice.
Stay true to yourself. Make your practice about yourself. Remember you are unique and so is your practice. And being able to do a handstand or a deep backbend doesn’t make you a yogi, and certainly not an advanced one.
