Universally we all love our childhood. Without analyzing much, if one ask themselves about the most happiest moments, it will invariably be from their childhood. No matter how old we become, how many experiences we have, the new connections that happen, places we travel, our childhood is always a period of our life to cherish. Take a deep breath and test yourself.
Psychologists even suggest that we look back deeper into our childhood, and pickup a thing or two from the past, in order to beat depression and to bring back a lost meaning in life. Such is the powerful association of happiness and childhood.
A common explanation for this universal phenomenon is that as a child we have nothing to worry about, everything is taken care of, we do not have bills to pay, or taking care of others. A carefree state of mind results in a happy situation. This reasoning is largely true.
However, we do observe today people who are affluent as well as with folks around them, who need not really have to take care of things on a day to day basis. We do see people whose needs are either small, or their affordability is high, so that without effort they are all taken care of. We see people who are well into their old age, taken care of by their children. It does happen. Even in these cases the elderly person longs for his or her childhood. The childhood always seems much more happy.
The deeper reason behind this joy of childhood lies in the fact, as a child we feel a Oneness with everything else in this world. A little ant, a house fly, a butterfly, a little toy soldier, our dad and mom, our grand parents, uncles, aunts, brothers, sisters, cousins and friends, all of them are part of us. Our sense of individuality has not yet matured strong enough to distinguish , differentiate and discriminate our self from the rest of the world. We live in a world where we are the only entity and everything else is a fascinating and fun part of our own self. we enjoy the world much deeper in this state. We live in a matrix of trust, and a nest where there is nobody existing outside of our self to hurt us.
Realizing the truth that we are indeed One with the rest of this Universe, will take us instantly back into the joyful state of Childhood. In a world, created by our own self for uninterrupted entertainment, there is no one else to hurt or harm, all is for our own Joy. Knowing this, not only explains childhood memories but helps us have that very joyful life this very moment, no matter how old we are.
