India is known for the cults of several Gurus, offering knowledge in regard to spiritualism as well as religiousness. These Gurus have promoted spirituality, meditation, love, peace, brotherhood, serving others and other humanitarian values to people in India and the rest of the world. Regardless of age, all followers of a guru are like his children. From misery and distress, He gives them shelter and imparts to them the knowledge of self-realization without expecting anything in return. The gurus also teach meditation and other methods for realizing the God who resides within. Now the question comes in mind that how does one can find a Guru? According to an ancient saying `when the disciple is prepared, the guru appears. A genuine spiritual guru seeks out good students. If he finds that the student is not yet ready, he will gradually prepare him for higher teachings. And when the wick and oil are properly prepared, the guru lights the lamp`.

Thus a Guru is a teacher in Hinduism, Buddhism, and Sikhism, as well as in many other new religious movements. A Guru is the person who determines each and every pace his disciple and guides him to the way to liberation of soul and salvation. In these religions, the guru is seen as a sacred channel for wisdom and a way to self-realization. In Sanskrit, `Guru` also refers to Brihaspati, a Hindu divine figure. Guru or Brihaspati is believed to exert teaching influences, in Vedic astrology. Indeed, in many Indian languages such as Hindi, the Thursday is called either Brihaspativaar or Guruvaar (vaar meaning day of the week). The word `guru` is widely used in concurrent India, with the general meaning of `teacher`. In Western usage, the original meaning of guru has been extended to cover anyone who acquires followers. They might not necessarily in an established school of philosophy or religion. Guru is used to refer to a person in a further Western metaphorical extension, who has authority because of his or her perceived secular knowledge or skills.

The importance of finding a guru is emphasised in Hinduism who can impart transcendental knowledge (vidya). A person without a guru or a teacher (acharya) in Indian culture was once looked down on as an orphan or unfortunate one. In an understanding, the Gurus are the instrumental in leading the mankind to the God. As because Gurus lead to God, are said to be greater than God. The transmission of teachings is called the guru-shishya tradition.
