There are four lines of disciplic succession: one from Lord Brahmā, one from Lord Śiva, one from Lakṣmī, the goddess of fortune, and one from the Kumāras. The disciplic succession from Lord Brahmā is called the Brahma sampradāya, the succession from Lord Śiva (Śambhu) is called the Rudra sampradāya, the one from the goddess of fortune, Lakṣmījī, is called the Śrī sampradāya, and the one from the Kumāras is called the Kumāra sampradāya. One must take shelter of one of these four sampradāyas in order to understand the most confidential religious system.
