Random House Webster’s give these as its first two definitions of the word unique: 1. Existing as the only one or as the sole example; single; solitary in type or characteristics: A UNIQUE COPY OF AN ANCIENT MANUSCRIPT; 2. Having no like or equal; unparalleled; incomparable: BACH WAS UNIQUE IN HIS HANDLING OF COUNTERPOINT. Each atma or soul is unique, just as each voiceprint, each fingerprint and each snowflake has a singular identity. The variety exists in the spiritual world, but is unseen by the impersonalist philosophers. Srila Prabhupada evokes metaphor of birds in trees to illustrate how people are easily deluded into impersonalism. From a distance one cannot distinguish the form of a green bird in the leafy greenery of a tree. But when one gets close, one can see that the tree is not all a mass of greenery but that individual atmas, the green birds, each with its own individuality sit in the tree.
