I read this in an forwarded email with Q&A. The question asked was about Swami's absence in the physical form. Swami's response was
"Always, at every time, at every place, I am where you need me. All things without are subject to the limitation of time and space, to the material laws of Nature. My outer form is no exception! If you would perceive my physical form, it must come within the range of your gaze, so position yourself so that you can see it. And even then, it may not gaze at you. But, I am omnipresent! The limitations of the body and the outer senses do not hold for the inner vision. Therein, you can see me at any time and any place and receive darshan. The outer vision is purposely insufficient, instantaneous, transitory, casual, so that you may crave for and accomplish the inner darshan. If I have separated you from my physical image off and on, it was only to bring you to me and to establish my presence within you. That alone will replenish you and refresh you, I know."
