The principle of organ donation is an interchange of material and the consciousness within it. This interchange opens a door of transaction which may not necessarily be good, especially if the body has received imprints from the Divine which cannot be shared casually and unconsciously with anyone. It is in this context that the Mother had told Champaklal ji not to donate his eyes as they belong to Her.
But while this is true of those who have evolved beyond a point, this need not be turned into an absolute rule for everyone. Most human beings live as an unindividualised mass consciousness, and interchanges of various kinds hardly impact them. The rule is mainly for those who have progressed beyond a point and gathered within it various spiritual imprints.
Affectionately,
