Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
His transcendental body, unlimited in length and breadth, occupied the three planetary systems, upper, middle and lower. His body was self-illuminated by unparalleled dress and variegatedness and was properly ornamented.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The length and breadth of the transcendental body of the Supreme Personality of Godhead could only be measured by His own measurement because He is all-pervading throughout the complete cosmic manifestation. The beauty of material nature is due to His personal beauty, yet He is always magnificently dressed and ornamented to prove His transcendental variegatedness, which is so important in the advancement of spiritual knowledge.
