"Bhakti Yoga, the path of devotion, consists of surrender to the Divine within the heart. The Maharishi considered the most important yoga path after self-enquiry and usually recommended the two together. Surrender [Bhakti] can be done in four ways:To the Supreme Self (Atma-Bhakti);To God or the Cosmic Lord as a formless being (Ishvara-Bhakti);To God in the form of various Gods or Goddesses (Ishta Devata-Bhakti) and ; To God in the form of the Guru (Guru-Bhakti)."
