ISHVARA PRANIDHANA
Light On The Yoga Sutras Of Patanjali B. K. S. Iyengar
II. 45 samadhi siddhih ishvarapranidhana
"samadhi" = deep absorption of meditation, the state of perfected concentration
"siddhih" = attainment, mastery, accomplishment, perfection
"ishvara" = creative source, causal field, God, supreme Guru or teacher
"pranidhana" = practicing the presence, dedication, devotion, surrender of fruits of practice
Surrender to God brings perfection in samadhi
Samadhi is attained through clarity of intelligence and intensity in thought to surrender to God. The power of samadhi comes to him who takes refuge in God
Surrender to God releases the sadhaka from the bondage of earthly desire, leads to the renunciation of sensuous desires, and nurtures in him the most intense form of application
