Self-Realization is not about attaining or discovering some exalted spiritual state, ecstasy, or Samadhi even though that is what you get when you read Ramana's students.
Self-Realization is finding that breath of life within you that is you, and just abide there. That I am sensation is illusive. You can grab it for a moment, two moments, but staying there is difficult. And lots of unsuccessful practice will dry you out.
But if you are dying or intensely in love, the Self comes alive as it did for Ramana when he felt his body dying. Everything intensified, and intensely attentive, he was a able to grasp the entirety of the "force of his entire personality" as well as the full energy of his life force which gave the body life, which held the body within its awareness.
It is easier to discover that Self that you are, not in the quieter transition states, but when you burst with energy and feel your body brought alive by the force of your own awareness, which you are.
