Prabhupāda: So the ultimate aim is liberation from this conditional life, bondage. We are conditioned in every way, we can experience. As soon as we are embodied with a material body, immediately we are conditioned.
Just like as soon as we enter in some state . . . just like we have come from India. I have come from India in your state. So I am immediately conditioned by the immigration department.
So this is the material world, this is the system. As soon as you enter a particular type of body you are conditioned. Just like while walking in the St. James Park the ducks and the swans, when they saw that we are coming near, they immediately dropped into the water. Because the duck is thinking that he's safe in the water. And if somebody snatches me to put me down in the water, then I shall protest.
He's also a living entity; I am also a living entity. I am afraid of being put into the water, and he is seeking shelter into the water. Water is the same. Why one is seeking shelter, and why one is afraid of? This is material world. Because I am conditioned in a separate body and the duck is conditioned in a separate body. The trees . . . some trees are going upwards, and some trees are going downwards. These are the conditions. Deha-yogena dehinām (SB 7.6.3).
So we are being put into different conditions, under different types of body. So liberation means that one shall not be under any condition. Just like Kṛṣṇa: He is not under any condition. That is liberation. We can also, because we are part and parcel of Kṛṣṇa, we can also become without any condition. Just like Nārada Muni. Nārada Muni is traveling in the space because he's liberated soul. He's not conditioned. But because we are conditioned, we cannot travel in the space without the help of some machine or something else.
This conditional life is going on anywhere you go within this material world. There are innumerable universes, and each and every universe, there are innumerable planets of different climatic conditions. Just like we find the climatic condition in the moon is different from the climatic condition of this earth. The climatic condition of sun is different from the climatic condition in the earth or from the moon. Every, each and every planet, each and every universe is differently conditioned. That is the beauty of Kṛṣṇa's creation. Keśava tuwā jagat vicitra. Bhaktivinoda Ṭhākura has sung, "Keśava, my dear Lord Kṛṣṇa, Your creation is so full of varieties." That's a fact.
But all these conditions are not very liking to us. We are trying to be liberated from all conditions. Therefore liberation is the ultimate goal. As it is here stated, "Religion includes four primary subjects, namely, pious activities, economic development, satisfaction of the senses and, finally, liberation from material bondage."
