Pranayama the body becomes lean, strong and healthy. Excretions become scanty and the appetite becomes keen. The digestive fire is augmented. There is lustre on the face and the eyes sparkle like diamonds. The practitioner becomes very handsome. The student becomes so perfect in brahmacharya, sensual restraint, that his mind will not be shaken even if a celestial maiden tries to embrace him. The student is free from all sorts of diseases. The nadis, flows of energy, are purified.
