(Sādhaka): “Accomplisher,” a spiritual practitioner; someone who follows a particular spiritual discipline with the aspiration to purify any inner limitations and thus, reveal the Consciousness of Oneness. According to the Shiva Samhita (5:10-14), there are four types of practitioners, depending on their enthusiasm, energy, character, style of yoga practiced, and commitment to the spiritual process: mild, moderate, ardent, and the most ardent—those who can naturally cross the ocean of the relative world.
