People are not interested in spiritual life.
At the present moment in Kali-yuga, people are not well educated. They are simply engaged in earning money to fill the belly. Vedanta philosophy is not meant for an ordinary person, not even for an ordinary learned person. It requires great knowledge of Sanskrit and philosophy. Of course Caitanya Mahaprabhu, being the Supreme Personality of Godhead, knew all things, but at that moment He had assumed the role of an ordinary person in order to instruct an illiterate, ignorant society. In this age people are not even interested in reading Vedanta-sutra. People are so badly infected by the influence of maya that they do not even care to understand that there is life after death or that there are 8,400,000 life forms. Sometimes if people hear that by acting in such a way they will become a tree, a dog, a cat, an insect or even a human being, they say that they do not even care to know this. Sometimes they say, “Never mind if I become a dog. What’s wrong with that? I will simply forget everything.” Many university students in Western countries speak this way. They have become so ignorant that they are described as manda. Previously, in India, the brahmanas were interested in understanding Brahman. Athato brahma-jijnasa. However, at the present moment everyone is a sudra, and no one is interested in understanding Brahman. People are simply interested in getting more money and going to the cinemas.
