1. The symptom of mukti

    When we speak about the Krsna consciousness movement, which is meant to make people intelligent, the conditioned living entity therefore misunderstands it. He is so engrossed in the material concept of life that he does not think there can be any activities that are actually based on intelligence beyond the construction of skyscrapers and big roads and the manufacturing of cars. This is proof of mayayapahrta-jnana, or loss of all intelligence due to the influence of maya. When a living entity is freed from such misconceptions, he is called liberated. When one is actually liberated he no longer identifies with the material world. The symptom of mukti (liberation) is that one engages in spiritual activities instead of falsely engaging in material activities.
