Spiritual life means normal life, and material life means diseased life. Therefore we are always suffering in materialistic way of life. Diseased condition means suffering. So when we have got suffering, how we can say, "It is normal life. It is healthy life"? The common sense. Can any materialistic way, those who are living in a materialistic, can say that "I am very happy"? No. That cannot be. That cannot be. This is diseased condition. One who is intelligent, he can understand that "This is diseased life. Why I am suffering?" That is intelligence.
Just like Sanātana Gosvāmī. He was minister, a very big post, government minister, chief man. Not only minister-Nawab Hussain Shah entrusted the whole kingdom in his hand: "You manage, whatever you like." Because he knew that "Here is a trustworthy man. He'll do very nicely." And he was a Muhammadan Nawab, so he was engaged in hunting and dancing with girls. But he was confident that "Sanātana is there." His name was changed, Sākara Mallika... Dabira Khāsa. His name was Dabira Khāsa, and his brother Rūpa Gosvāmī's name was Sākara Mallika. They almost became Muhammadan. Very responsible officer. When they wanted to resign, oh, Nawab Hussain Shah became topsy-turvied: "Oh, what do you say? I am depending on you. The whole thing is depending on you. And you want to resign? Oh, you have gone crazy. I cannot allow you." So actually... But he was thinking... Since he met Lord Caitanya, he was thinking that "I am diseased. What is the value of my this education and this post? I am diseased."
