Epitome of Equality

First of all This is not to demean any religion.. I am a Hindu by birth, but yes I respect all religions .I offer my daily prayers , fast on holy days , but there was something that was disturbing me . God as per me was a Friend, someone who was by my side always , someone who was a dear friend , but this is not what everyone else thought , for others he was the Judge who gives his verdict always and punishes anyone and everyone .

I have had too many experiences where I was treated as a second class citizen in the temple . Why? Well I could not afford giving thousands as donation. This is not how it should be , God looks at each one of us with the same divinity .As I mentioned God for me is a friend, so tell me, do we chose friends based on their bank balances? Do we give our verdict on them ? then how can God do it? I know many of us would ...

When family hurts: A tale of love, loss, and liberation

In the shadow of the Jasmine tree: Breaking free from a toxic family In the decaying splendour of Eyrevale Manor, Elara battles toxic parents, rekindles forbidden love, and questions whether she can escape the chains of her upbringing. Under a canopy of jasmine, secrets are shared, hearts break, and truths unravel. Set in an enchanting town, this story examines love, loss, and the painful pursuit of self-discovery. What happens when home feels like a battleground? No one warns you how heavy a homecoming can feel when the word home means nothing to you. If there is one universal truth, it is this: not all homes are sanctuaries. For some, they are labyrinths of unspoken grudges, passive-aggressive remarks, and familial obligations wrapped in barbed wire. My story, dear reader, begins in the sweltering heat of Eyrevale—a coastal town so humid it could curdle your very thoughts. And for me, Eyrevale wasn’t just oppressive because of its climate. No, it was the family home that truly choke...
