This is a very relaxing and uplifting prayer meditation, in which you keep smiling to Ishta Devata, in the altar of your heart centre, and pray for antahkarana shuddhi. It fosters a deep sense of connect with Ishvara, at an emotional level. It is adapted from Irmansyah Effendi's Open Heart Meditation.
