According to Osho, simply being in the presence of a meditative field (satsang) begins to dissolve karmic residues. Your presence here is both an outcome of past tendencies and an opportunity: if you participate meditatively and receptively, the chain of cause and effect weakens or ends; if you remain closed, you create fresh karma of missed opportunity and delay your flowering.
Sitting near a lit candle can light your own; if you open and sit quietly, old knots melt, but if you close off, you tie new knots.
