A powerful quote and a great quote from Lao Tzu.
If you understand yourself you have (are) the power. You are like a light illuminating with power when you know, about yourself.
Any kind of wound (emotional) should be let go. Connect to your inner self. Heal it (whatever you are going through), feel it (sense and let go of that situation) and welcome the peace into you.
Having peace is power.
No emotional disturbance can knock on your heart. It is like having a signboard ‘you cannot disturb me’. Not that we should not have emotions. Yes, we all have emotions. However, managing these emotions is difficult.
We are like sponges. We absorb the dirt (wounds/emotions). To dry and bring it back to the original we have to squeeze (let go) and clean our wounds (emotions).
Otherwise, it (the heart) is heavy and it takes time to dry down itself.
What we can achieve from this is as soon as we let go we have space for peace as well as time for other things in life rather than harvesting (hurt/wounds/emotions) inside and feeling down.
Empower yourself by knowing you yourself better.
