Have you ever noticed a waterfall ? Have you ever been near to it?? Have you ever thought what it stored in for you??
I’m pretty sure it wants you to be like them. What i mean to say is just be like a floating water.
Have you ever catch a sight of any stack of litter,debris,waste or mud at corner waiting for someone to pick it up and dump?

Such things remain unnoticed by many of us.

It keeps them throwing out sometimes with little effort(pressure) , at times with some extra effort(heavy pressure). Thats the Reason it is so clean n pure that u can see the earth through it. So, when you hear the sound of waterfalls it is so serene,soothing,hypnotizing, it gives you a peace of mind.

Like wise,you need to throw out ego,negative attitude,grudge, hatred, envy, jealousy, worries,negativity from your heart. Be aware that sometimes it will take little effort and sometimes extra effort to take that burden out. When there’s no burden on mind and heart, your life will be at peace and tranquility.
That’s when your laugh will be so pure that it will leave everyone amused.
