Darkness is nothing but our intuition of thoughts. Is there anything in this world is useless? Do you take it seriously? Is there any explanation regarding the kinds of darkness? Some optimistic has given their description on the positive side of darkness. In my view darkness is nothing but just a rest to look back on our failure that is very important for going forward because for a long journey we need to collect all our memories so that we can achieve whatever we want. Alacrity in our efforts keeps away us from the hidden happiness so nature has presented plethora for us to understand the single point of our stupendous efforts. Head and tail are the two complement for each other similarly this can be seen in nature in the form of darkness and light.
