"Sadguru gurudeva on Nandi deva"
He is in waiting. The Nandi is a symbolism of eternal waiting, because waiting is considered the greatest virtue in this culture. One who knows how to simply sit and wait is naturally meditative. He is not expecting Shiva to come out tomorrow; he will wait forever. That quality is the essence of receptivity. The Nandi is Shiva’s closest accomplice because he is the essence of receptivity. Before you go into the temple, you must have the quality of the Nandi, to simply sit. You are not trying to go to heaven, you are not trying to get this or that – you go inside and simply sit. So, just by sitting here, he is telling you, “When you go into the temple, don’t do your fanciful things. Don’t ask for this or that. Just go and sit like me.”
The quality of the Nandi is that he just sits,alert.This is very important: he is alert. He is not sleepy, he is not sitting in a passive way; he is sitting, very active, no expectation, no anticipation, no looking forward to anything; full of alertness, full of life, but just sitting and that is meditation. Just waiting. Not for anything in particular. If you just wait without doing your own thing, then the existence will do its thing. Meditation essentially means the individual person is not doing his own thing; he is just there. So, once you are simply there, you become aware of the larger dimension of the existence, which is always in action. You become aware that you are a part of it.Even now, you are a part of it. But becoming aware that “I’m a part of it” is meditativeness. So, the Nandi is the symbolism of that. He just sits. Sitting here, he reminds everybody, “You must sit like me.”
