The term 'Shaft of LIGHTNING' is composed of two words, 'BOLT' and 'LIGHTNING'. BOLT is a four-letter word which refers to a sudden, powerful, and usually destructive discharge of electricity in the atmosphere. LIGHTNING is a natural phenomenon that occurs when electrical charges build up in the atmosphere and are discharged in a powerful flash of light. Together, these two words form the phrase 'Shaft of LIGHTNING', which is used to describe a powerful beam of light that is created by a LIGHTNING strike.
