In Shaiva Tantra, the role of a guru is considered to be of utmost importance. A guru is seen as a spiritual guide and teacher who helps the practitioner on their path towards self-realization and union with Lord Shiva. The word guru is derived from the Sanskrit words "gu" meaning darkness and "ru" meaning remover, indicating that the guru helps to remove the darkness of ignorance and guide the disciple towards enlightenment.

The guru-disciple relationship in Shaiva Tantra is considered to be sacred and is based on mutual trust, respect, and devotion. The disciple surrenders to the guru and follows their guidance and teachings with complete faith and dedication. The guru, in turn, takes on the responsibility of guiding the disciple on their spiritual journey and helping them overcome any obstacles that may arise.

One of the main roles of a guru in Shaiva Tantra is to transmit the teachings and practices of the tradition to the disciple. This transmission is known as shaktipat and is considered to be a powerful initiation that awakens the kundalini energy within the disciple. The guru also provides the disciple with a mantra or sacred sound that is used in meditation to connect with Lord Shiva and attain a state of non-dual consciousness.

Apart from transmitting knowledge and practices, the guru also serves as a role model for the disciple. They embody the principles and teachings of Shaiva Tantra and inspire the disciple to follow the same path. The guru also helps the disciple to develop qualities such as compassion, selflessness, and detachment, which are essential for spiritual growth.

In Shaiva Tantra, the guru is also seen as a mirror, reflecting the true nature of the disciple and helping them to recognize and overcome their ego and limiting beliefs. The guru guides the disciple towards self-awareness and self-realization, helping them to understand their true nature as a reflection of Lord Shiva.

In summary, the role of a guru in Shaiva Tantra is multifaceted and crucial. They serve as a teacher, guide, role model, and mirror, helping the disciple to awaken their true potential and attain union with Lord Shiva. The guru-disciple relationship is based on trust, devotion, and surrender, and is considered to be a sacred bond that leads the disciple towards spiritual liberation.
