Looking into my first nephew's face.
"He's our next generation. He's our baby. The world is no longer about just enjoying myself and finding myself. There's a higher purpose outside of myself.
"Yes, he has parents who I am sure feel that way times 10. And I know I'm only his aunt and obviously its his parents' places to really sacrifice for him. But he's my nephew. I feel a responsibility to him, too. I feel a responsibility to help him have the most amazing life and achieve all of his dreams.
"Another nephew and a niece later, I feel the same thing for each one."

When my grandmother died.
"You end up in the ground, and that's that.
"It was then that I realized that Heaven/Hell/Purgatory does not exist. The purpose of life is not to do good things to get in to heaven, or to please some deity that may be waiting for you with open arms because of all the praying you did.
"It's to do great things that make things more amazing for those that you will leave behind. To make people remember what you did with the time you were given."

"I started believing in some cosmic forces of nature, due to some uncanny things happening at multiple music festivals for me."

Having to put my cat down.
"I also felt this while visiting my grandpa just before he passed away and again at his funeral. At his funeral reception, the whole room suddenly went from sad and gloomy to happy and cheerful. The event became more of a happy celebration of his life. Sometimes I will feel this presence. The room I am in will smell like my grandpa or cat, and it will feel like they are in the same room as me."

Seeing the blackened death metal band Behemoth in concert.
"A bit of backstory: Behemoth has always been a very brutal band, obsessed with speed and pretty much just a solid death metal act. Their lead singer, Nergal, was just as you would expect the front man of such a band: long haired, sort-of muscular, generally badass looking and quite charismatic. Then, in 2010, he was diagnosed with Leukemia.
"...Then I go to one of the concerts on their first headlining tour since the illness. They have always had a flair for the occult, but this time it's all out. Altars, candles, incense, costumes, face paint, blood, the works. When they started playing, I was immediately struck by how disfigured Nergal looked. He was gaunt, his face was shriveled, and his limbs were barely there. If I had seen him on the street, I wouldn't have expected him to be able to walk. After the first couple of songs, the music stopped. He took down his hood. He was bald. Then he spoke to us, and all he said was, 'It's good to be alive!'
"After that, they played the most energetic show I have ever witnessed. This man who looked like he would be broken in half by a stiff breeze was running, jumping, sliding, screaming, riffing, soloing and just living with this unmatchable vitality. It was the only time where I believed that there might be a God, because I was watching a man who had beaten him. It was a celebration of freedom from divine will."
