I used to categorize my spirituality and associated beliefs as "non-dual" without hesitation, and that has changed. It's a tricky toss up these days to know what someone is pointing to when they use that term....
When non-dual is stated as a triumphant defeat of duality and multiplicity, I'll agree to disagree, because my answer is it's a both/and win-win. When it points to the co-dependent reality of oneness and separateness and that the spiritual and the material are inextricably interwoven, I'll be smiling from my heart. When it refers to a false split between spirit and matter my heart will sink. When it points to balance and healing fragmentation, I'm totally in. When it's a rally cry for a war against the ego, I'm running. When it points to inter-connection, and self-compassion, I'll stand for that. When it supports inter-personal communion rather than impersonal intimacy, amen. When it encourages and celebrates self-expression, soul flourishing and societal repair, hallelujah. If it signals pitting god against its' humanity, or the ego against itself, I ask you to reconsider. When it incites disdain for humanity, apathy or nihilism, I'll pass. When it's renunciate, hollow, ascetic, and cold, I'll pass too. When it points to the ground of being blossoming, I'm right there with you, seeing the extraordinary in the ordinary, jumping for joy and sorrow, and everything precious in between.
