Meditation on one principle using the method of samāpatti (habitual engrossment of mind on the object of contemplation through momentum of diligent effort) is considered especially fruitful for beginners. That one principle can be either: Ananta samāpatti which is engrossment in emptiness or Iśwara samāpatti which is engrossment in godliness. Both rely on attainment of calmness and bring about mindfulness.
Engrossment in emptiness bears the thesis: I am the observer of all fluctuations that are arising in my mind. A recollection of such an ‘I’ as a support of contemplation brings calmness from the subtle feeling of void. This is also called the contemplation on I-sense. Iśwara is described as that Being who is free from all afflictions, karma and its results, bereft of any subliminal impression other than tranquility. The best English translation of Iśwara is God. Engrossment in godliness invokes a singular contemplation that one is immersed in God but within one’s own heart.
Seekers who prefer the more intellectual path of knowledge often choose the practice of engrossment in emptiness. Whereas devotees lovingly connect with the practice of engrossment in godliness. Both types of guided meditations are available to try and are suitable for all aspirants.
