Clean and dirty both water we get from the ocean. It depends on you how will you filter the water of the ocean. It depends on you which water (clean/dirty) will you carry with you. If you take the water which is flowing near the beach, you will not get clean water. If you go a little towards the mid of the ocean, you will get clean water easily.
Our mind is like a big ocean where both positive and negative thoughts are flowing. It depends on you- which thoughts you will carry and give shelter within you.Inspired by:
