The experienced ones, many times more intelligent than us. You forget, you shall also be old one day and the same fate shall befall all of us. Woe to humans who fail to understand themselves. What a pity. We boast of understanding others but we do not see the divinity inherent in all.
Humanity is on the threshold of being annihilated.
You would never get a second chance. Before it is too late. So that every human being has to struggle to proceed ahead on its Earthly journey. He has to do his Karma and also not to worry of the fruits. Man made systems will crumble in a short time.
