Even if we use quotes of Swami and we talk about his words, as soon as we speak that are our words as well. We are the same or we are not, but we cannot speak Swami's words without using our own words.
But we use his words, we know we use his words and not our words, because I had no words for it, he made me see it, therefore, that are his words and not mine, it just sounds like my words, because we are his instruments.
But we know it is the right thing to do using his words and why, because he is the Atma, in using his words, we get the insights and he is as well the following step and the answer to the insights.
He is the Atma, he is the ocean, we are the waves. He is the doer, we are the instruments, he is the knower, we are the instruments. When we use his words, we begin to understand oneness, because he is repeating it on and on, and that are his words, do you think we would talk about oneness without Swami's words?
