Ekasarana Dharma is a belief system that says there is only one way to find God, and that is through devotion to a deity called Lord Krishna. Imagine Lord Krishna is like your favorite superhero – if you want to talk to him, you have to think about him a lot, talk to him every day, and try really hard to be like him.
In Ekasarana Dharma, it is believed that Lord Krishna is the most powerful and loving god, and by dedicating your life to him, you can become closer to him and find inner peace. It's like having a best friend who makes you happy, helps you when you need it, and always knows how to make you feel better.
People who follow Ekasarana Dharma usually pray and sing to Lord Krishna, and try to live their lives in a way that would make him proud. They also try to help others and be kind, just like Lord Krishna would want them to.
So, in a nutshell, Ekasarana Dharma is all about devotion to Lord Krishna and trying to be a good person, just like he is.
