Six blind men touched different parts of an elephant - one felt the leg and said it was a pillar, another the tail and called it a rope, one touched the trunk and claimed it was a snake, and so on. Each was convinced of their own version, yet none grasped the whole truth.
Vedanta uses this story to show how limited perception leads to partial truths. Just like the blind men, we often mistake the part for the whole when trying to understand reality.
The elephant represents Brahman; the infinite, indivisible truth. Our limited senses and mind can only perceive fragments, but the essence of Vedanta is to go beyond the limited and realize the One that pervades all.
Truth is not many — it is One, seen through many lenses.
