The practice of the Noble Eightfold Path from moment to moment during intensive meditation retreat or in daily life can lead to peace, happiness and liberation/freedom.
Reflections after just having returned from retreat, on (1) the nature and beauty of retreat, (2) the range of practices done---concentration, insight, metta, and open awareness; and (3) the deep intention to connect retreat and daily life.
For those, who struggle with the advaita/ non-duality teachings, the yoga also offers the alternative and/or additional practice of "surrender to God", a devotional practice. Readings of the mystic Kabir are used to illustrate the devotional aspects of the yoga practice as lied down in the Patanjali Sutras.
