Only humans can know God
God can only be known by the human beings and not by the animals. For the animals God will be unseen, unknown, and unknowable. Those humans who cannot describe God are fallen to the consciousness of animals.
SB 11.26.1The Supreme Personality of Godhead said: Having achieved this human form of life, which affords one the opportunity to realize Me, and being situated in My devotional service, one can achieve Me, the reservoir of all pleasure and the Supreme Soul of all existence, residing within the heart of every living being.
SB 11.26.2A person fixed in transcendental knowledge is freed from conditioned life by giving up his false identification with the products of the material modes of nature. Seeing these products as simply illusion, he avoids entanglement with the modes of nature, although constantly among them. Because the modes of nature and their products are simply not real, he does not accept them.
One should never associate with materialists, those dedicated to gratifying their genitals and bellies. By following them one falls into the deepest pit of darkness, just like a blind man who follows another blind man.
