The Mother Herself has confirmed that Pondicherry is immersed in vibrations of the Ashram and Their Presence. But living within a certain zone of vibrations is one thing and opening ourselves to these divine vibrations is another thing. We may be surrounded by water but our vessel may be closed and turned upside down. So while it is true that those living near the Ashram and the Samadhi are automatically bathed in certain vibrations that many can feel when they come from outside, we may yet not be able to take the most out of it if we remain closed in the ego-self or be driven by desires and fears. Certainly the atmosphere will help but there is something that we still must do.
Of course it is also true that though Her physical atmosphere extends much far than the physical limits of what we call as the Ashram Main Building where the Samadhi is located, it is equally true that as it extends further there is a covering effect of the human atmosphere that increasingly tends to create a kind of cover. At the same time and on the other hand wherever one may, even far far away on the other side of the earth one can come in active contact with the Mother since Her Presence is everywhere.
