Senses are there, and those senses are required to be used; otherwise there is no meaning of senses. But that is spiritual. So senses have to be engaged in the spiritual activities. That is spiritual life. Spiritual life. The example, as I have already explained to you many times, just like Arjuna. He wanted to control his senses to refrain from fighting. When you fight, you require to engage your senses. He said that "I will not fight." That means he is controlling his senses from fighting. But after hearing Bhagavad-gītā, he says: "Yes, I'll fight."
Just see. Before hearing Bhagavad-gītā, the position of Arjuna, that "I," "I will not fight," and after hearing Bhagavad-gītā, the position of "I," "Yes, I will fight." Two contradictory. Before hearing Bhagavad-gītā, the position of "I" was negative, and people may estimate this nonviolence attitude of Arjuna very nicely.
But after Bhagavad-gītā, after hearing Bhagavad-gītā, he says: "Yes." Kariṣye vacanaṁ tava (BG 18.73): "Yes, I shall fight." Now, do you mean to tell that he degraded? First of all he was nonviolent; he was not willing to fight. Now he has degraded after hearing Bhagavad-gītā? Is it the conclusion? No. He has improved. He has improved. Why he has improved? Because he has understood how to use the senses. That's all. In the beginning he did not know how to use the senses. Therefore he decided, "I shall not fight. I shall not fight." That is his material calculation.
