If you visit a temple, you can see pictures of God, you can see the Deity form of the Lord, and you can just hear Him by listening to yourself and others say the mantra. It's just a way of realizing that all the senses can be applied toward perceiving God, and it makes it that much more appealing, seeing the pictures, hearing the mantra, smelling the incense, flowers, and so on.
George HarrisonIf you drive a car, I'll tax the street; if you try to sit, I'll tax your seat; if you get too cold, I'll tax the heat; if you take a walk, I'll tax your feet.
George HarrisonSome things take so long But how do I explain When not too many people Can see we're all the same And because of all their tears Your eyes can't hope to see The beauty that surrounds them Now, isn't it a pity
George Harrison
