Strangely enough, Ayahuasca/DMT/psilocybin seem to consistently push my spiritual interests in the direction of Christian mysticism. However, I haven’t had much of these in recent years, so have been mostly drawing spiritual inspiration from my usual, Buddhist sources.
Incidentally, it’s not uncommon to hear American Buddhist/Buddhist-adjacent teachers like Adyashanti and Tara Brach referencing Christian scripture. For example, Tara Brach has a great talk inspired by the book, Return of the Prodigal Son, by the late theologian, Henri Nouwen - wherein, Nouwen discusses the symbolic meaning of this parable through the lens of the famous Rembrandt painting the book is named after, which depicts the reunion of the son and his father.
According to Nouwen, the wayward younger son, the judgemental older son, and the forgiving father all represent different aspects of the psyche, with the father symbolizing our highest/deepest human potential, as the archetypal embodiment of the inner divine.
Another great book is The Universal Christ, by the contemplative Franciscan teacher, Richard Rohr. This book lays out the vision of incarnational Christianity, which I see as the core of Christian mysticism, or the possibility of spiritual union that exists for everyone, irregardless of their connection with Christianity, or lack thereof.
