In the past, gurus were the main source of spiritual knowledge to people, because only they possessed the secret knowledge of the Vedas and other scriptures
Globalisation has extended the guru's reach into environments where they may be a stranger, and where the religion, purpose, and status of the guru is poorly understood
Many gurus are now public figures, their lives are open for public scrutiny as those of celebrities, politicians and popular figures
Their teachings are also publicly available through many sources and mediums
Tantric spiritual texts are often codified in an obscure twilight language so that it cannot be understood by anyone without the verbal explanation of a qualified teacher or guru
He may give you spiritual advice, which is specific to your personal needs
He may protect you from your own negative karma, and from evil influences of the world
When you are initiated, your guru gives you a guru-mantra, which can help you to focus your mind and engage in spiritual practice
He may clarify your doubts, correct your mistakes, resolve your karma, guide you in the practice of self-discipline and purification, serve as an example for others to follow, bestow his grace upon you and provide you with knowledge and clarification
