A house is like a life insurance -- it protects you, that's all. It is not life -- it doesn't feed you, doesn't nourish you. Ketan means a home, a love space. It is not physical really -- something inner... a different kind of quality. And you can feel it. If you go into a house where people love, where love flows, where love sings many songs, you can immediately feel a different quality to the atmosphere, a different vibe. It pulsates on a different wavelength. You can immediately become aware that this is a home -- the warmth, the welcome. Even if there is nobody and you are sitting alone in a home where people love each other, where love flows, you will feel the pulsation, you will feel accepted... as if the home is rejoicing in your presence. It is not rejecting you.  In a house everything is neutral. There is no welcome, there is no warmth -- it is cold. It may have a central-heating -- that is not the point; it is still cold. The coldness is psychological. It does not pull you -- it pushes you away.
