With advance of Krishna Consciousness one is able to realize that Krishna is always with His devotees — not only with His devotees, also with the non-devotees, but the devotees can recognize His Presence and the non-devotees cannot. The more you make advancement in Krishna Consciousness you will see Krishna everywhere. Not only on the bank of the river, but also on streets, trees, lampposts, and so on. The more you see like that you know you are making tangible advancement in Krishna Consciousness. Actually, there is nothing but Krishna all around us. This is explained in the Gita. He is the taste of water, light of the moon, the fragrance of the flower, light of the sun, sound of the sky, the power of the strong and so on. So one who is actually making progress in Krishna Consciousness, he can see Krishna everywhere. At every stage of life, who can avoid the sunlight, the moonlight, the fragrance of the flower, the taste of the water, the sound of the sky, and so on? But one has to learn it, that there is Krishna in all these varieties of existence. Without Krishna there is nothing. It is simply by the influence of Maya that we forget the relationship of Krishna with everything that be.
