Lord Caitanya in Jagganath Puri divided the kirtan and all the devotees into eight different parties and He appointed dancers and different kirtan leaders for each of these parties. But it is said that some could see that Lord Caitanya was Personally dancing in every party and had expanded Himself into 8 forms, but not everyone could see that! Some could see!
So sometimes it appears like that, that not everyone is capable of perceiving the transcendental appearance of the Lord or other mystical feats.
