It is our observation that most people (in America, at least--we can't speak intelligently about the rest of the world) are unhappy most of the time.
It is our further observation that it just doesn't have to be this way. Life doesn't have to be this hard.
Now, we're making no claims that these observations are in any way unique to us. The Buddha said the same things 2,500 years ago.
If the Buddha (and Jesus, and Muhammad, and whatever other enlightened sages you'd like to point to) couldn't teach people that they don't need to suffer, why are we so arrogant to think we have anything useful to add?
In part, it's that every voice that offers a path to any level of awakening is valuable--maybe one of those voices will speak to you. (I'd practiced both Zen and Vipassana meditation prior to meeting Jerry, but it was the simple practice of centering that unlocked the door for me.)
It's also that modern technology can serve to amplify a voice in a way that has never been possible before. (Unfortunately, as we've seen through such phenomena as online bullying and fake news, this cuts both ways.)
But more than anything, it's that we feel we've been called to help, and believe we can help.
