According to Osho, “deep sleep” in discourse has three roots: escapist dozing, habitual mind-resistance, or tandra—a yogic, sleep-like hush where thoughts stop yet hearing stays clear. In tandra you stand on the threshold, receive a rest deeper than sleep, and the words sink beneath memory. If it’s escapism, stop coming; if habit, persist; if tandra, relax and allow it.
Sometimes that “sleep” is just avoidance or habit, but sometimes it’s a calm in-between state where your mind rests, you still hear, and the talk sinks in deeper than memory.
