Whenever you see or hear the word Guruji do you really know what it means? In Hinduism, Sikhism and Jainism the meaning of the word "guru" is very similar in that it refers to a religious teacher or leader. It applies to one giving personal spiritual guidance to his disciples or followers. Sometimes and especially those involved in Vedic Astrology and Psychic Healing will call themselves "Guruji", when they have not really earned the respect of others or become entitled to use this term. The "ji" part is referred to as a respectful way of addressing the guru, much like you would call a man from the west "sir" or a woman "madam".
