If one takes to Krsna consciousness, in the beginning there will be many disturbances caused by Maya, the material energy of illusion. Maya will test us to see how firmly we are fixed in Krsna consciousness. Because she is also an agent of Krsna, she does not allow anyone the freedom to disturb Krsna. Therefore she tests very rigidly to see whether we have taken to Krsna consciousness to disturb Krsna or are actually serious. That is Maya’s business. So in the beginning there will be tests by Maya, and we shall feel so many disturbances while making progress in Krsna consciousness. But if we follow the rules and regulations and chant regularly as prescribed, then we shall remain steady. If we neglect these principles, Maya will capture us immediately. Maya is always ready. We are in the ocean, and at any moment we may be disturbed. Therefore one who is not disturbed at all is called paramahamsa.
