Definition - What does Antaratma Sadhana mean?
Antaratma sadhana is the final of the three stages of sadhana, meaning "practices," as described by the great sage, Patanjali, in his Yoga Sutras. Sadhana, or yoga sadhana as it may also be referred to, consists of three stages: bahiranga sadhana (external study or outward quest), antaranga sadhana (inner quest) and antaratma sadhana (innermost quest).
Yogapedia explains Antaratma Sadhana
The three stages of sadhana correspond with the eight limbs of Ashtanga yoga. The first three limbs - yama, niyama and asana - correspond with bahiranga sadhana. The next two limbs - pranayama and pratyahara - correspond with antaranga sadhana. The last three limbs - dharana, dhyana and samadhi - correspond with antaratma sadhana.
Bahiranga sadhana involves practices that use the body and prana to advance in a spiritual practice. Antaranga sadhana consists of practices that aid in deep study and cultivating the mind. Antaratma sadhana, the quest of the soul, promotes concentration, improves self-awareness, curbs external thoughts and achieves Self-realization. Antaratma sadhana helps the yogi to feel one with universe and experience eternal bliss.
