How to uplift one's Own Self?

" If I am a Pariah, I will be all the more glad, for I am the disciple of a man, who — the Brahmin of Brahmins — wanted to cleanse the house of a Pariah. Of course the Pariah would not allow him; how could he let this Brahmin Sannyasin come and cleanse his house! And this man woke up in the dead of night, entered surreptitiously the house of this Pariah, cleansed his latrine, and with his long hair wiped the place, and that he did day after day in order that he might make himself the servant of all. I bear the feet of that man on my head; he is my hero; that hero’s life I will try to imitate. By being the servant of all, a Hindu seeks to uplift himself." - Swami Vivekananda
(Complete Works of Swami Vivekananda . Swamiji's speech at Madras)

Swamiji mentioned this incident from  the life Bhagavan Sri Ramakrishna in the context of explaining how to uplift one's own self, by serving others whole heartedly. For those who have studied the life of Sri Ramakrishna, it looks like he is an orthodox person but this incident shows how reformist he is at his heart and how genuine he is when he says that serve every human being thinking that you are serving the god himself. This incident also shows us how to practically get rid of the Ahamkara(ego) by actually thinking and practicing  that 'i am the servant of the servants'. This is the unique way of doing things by Bhagavan Sri Ramakrishna.
