Sri Nisargadatta Maharaj

Nisargadatta himself tells of his time with his Guru, and what transpired in the more mature phase of his spiritual practice (sadhana):

My Guru told me: “...Go back to that state of pure being, where the ‘I am’ is still in its purity before it got contaminated with ‘I am this’ or ‘I am that.’ Your burden is of false self-identifications—abandon them all.” My guru told me, “Trust me, I tell you: you are Divine. Take it as the absolute truth. Your joy is divine, your suffering is divine too. All comes from God. Remember it always. You are God, your will alone is done.” I did believe him and soon realized how wonderfully true and accurate were his words. I did not condition my mind by thinking, “I am God, I am wonderful, I am beyond.” I simply followed his instruction, which was to focus the mind on pure being, “I am,” and stay in it. I used to sit for hours together, with nothing but the “I am” in my mind and soon the peace and joy and deep all-embracing love became my normal state. In it all disappeared—myself, my guru, the life I lived, the world around me. Only peace remained, and unfathomable silence.

Paramhansa Yogananda

God is the life behind your life, the sight behind your eyes, the taste behind your tongue, and the love behind your love. To realize this to the fullest extent is Self-realization. Without God's power you can do nothing. If you always hold this thought, you cannot go wrong, because you will have purified the temple of your mind and your soul with the vibrations of God.

The love of God uplifts and enlarges us. I can never think of myself anymore as exclusively in this body; I feel that I am present in all bodies. I have no awareness of race or other distinctions at all. In my perceptions, just as I feel my own consciousness in every part of my physical form, I feel you all to be a part of me. Everything that is living I feel within this body. I know the sensations of all. It is not imagination; it is Self-realization. This consciousness is far beyond telepathy. It is awareness of the perceptions of every being.

Swami Vivekananda

God alone is eternal, everything else is transitory. Everything dies; the angels die, men die, animals die, earths die, sun, moon, and stars, all die; everything undergoes constant change. The mountains of today were the oceans of yesterday and will be oceans tomorrow. Everything is in a state of flux. The whole universe is a mass of change. But there is One who never changes, and that is God; and the nearer we get to Him, the less will be the change for us, the less will nature be able to work on us; and when we reach Him, and stand with Him, we shall conquer nature, we shall be masters of phenomena of nature, and they will have no effect on us.
