What it means
The unshakeable-mind yoga — mind (Moon) grounded in a fixed sign and steadied by Saturn in a house of dharma. Classical texts describe the native as impossible to unsettle by ordinary means; even extreme events pass through them like weather through a mountain. Modern context: often marks the emergency-room doctor, the career soldier, the person friends call during their own crises. Not lack of feeling — capacity to hold feeling without collapse.
