In what can be viewed as both a positive and a negative of the Age of White Noise, social media has given us the opportunity to invent new selves - sometimes, it seems, a hundred of them, to be used for different people, situations, even moods. It has given us the chance to smile when we are crying on the inside, if we aren't feeling very brave, or if we feel like we need to put on one of those hundred different selves. It has allowed us to share our despair, our wonderful happiness, our big thinking, and our dreams. 

But what it has also done is laid us bare to criticism and a lack of care, both in our own actions and those of others. We cannot hide from hurtful situations. We cannot hide from what we say and do, and sometimes - achingly, angrily, and agonisingly - we cannot hide from what others say and do to and about us. 

John Lennon was a wise man by the time he died, and he knew what was what when he said the words 'instant karma's gonna get you'. The Buddha had his own time of mortification - imagine what it would have been like if it had been fed back to him on Instagram, and Facebook, and Twitter?
