The Tibetan word for mandala (Sanskrit for ‘grouping’ or ‘association’) is khyil-khor. Khyil-khor is a totally interpenetrating energy. It is not possible to exclude anyone from your khyil-khor or to be excluded from anyone else's. Ultimately, every being is part of your khyil-khor. Everyone and everything is linked with your field of energy; and you are linked with theirs. Therefore it is vital that we recognise this, or that we work towards this recognition. You cannot really ever feel comfortable in your own skin if you are attempting to be exclusive. It is not appropriate, or accurate, to exclude anyone or anything; because that would be attempting to do something that is not possible.
