In our experiences on the devotional plane, we can actually experience actual, honest self-realization, not sugar coated by speculations, schemes, or slippery slopes. The catch is that it's not easy, and it's not something you can easily purchase.
In this process, one begins to see the best and the worst of our character and conditionings. We can see and actualize the confident, loving, humble servant we eternally arer, but at the same time, we must deal with, face-to-face, all the roadblocks and weeds that are in the way.
Self-realization doesn't mean we try to stuff away our problems with some "secret" or some fancy poses and diet-tricks. It means we face up to what we're not so that we can become who we actually are.
Prabhupada writes in the preface to the Nectar of Devotion what real self-realization must include..
"At the present moment we are inventing so many ways to utilize our propensity to love, but factually we are missing the real point: Kṛṣṇa. We are watering all parts of the tree, but missing the tree's root. We are trying to keep our body fit by all means, but we are neglecting to supply foodstuffs to the stomach. Missing Kṛṣṇa means missing one's self also. Real self-realization and realization of Kṛṣṇa go together simultaneously. For example, seeing oneself in the morning means seeing the sunrise also; without seeing the sunshine no one can see himself. Similarly, unless one has realized Kṛṣṇa there is no question of self-realization."
