The death of ego
To dissolve the ego it is not enough to practice only in the morning and evening (although this is very important); you must learn to die moment by moment.
"The death of the ego in the unlimited Silence ( the non-dual Truth) and the shining forth of the Self is the attainment of Oneness (Kaivalya-Siddhi ). In that State of Jnana, pure Bliss will gloriously blaze forth as one’s own True Nature."
~Sri Ramana Maharshi
