It’s interesting to me that this began through a meditative experience. I stopped lying at some point, and it may have happened after taking a meditation class.
I think a big part of being honest with others is being honest with ourselves. Often we don’t look deeply enough within to even understand the truth behind our own actions. I would imagine that spending 10 days getting to know your own mind and meditating helped you to see your own truth, which in turn allows you to share truth/honesty with others.
These days when someone asks me a hard question that I can’t instinctively answer truthfully, I take a moment and check in with myself to understand my truth before I respond. Almost like an informal meditation.
I do agree that it is freeing. The honest answer usually makes more sense than a generalized excuse.
