Prabhupāda: Everything is Kṛṣṇa's energy. Kṛṣṇa is spiritual, therefore His energy is also spiritual. But in the spiritual energy there is the possibility of forgetting Kṛṣṇa. That is called material.
So if we remember Kṛṣṇa, that is not material. A man . . . (indistinct) . . . stone, wood, brick and constructs a big, high skyscraper building; that is material. But the same stone, same wood, same cement, you construct a very nice temple of Kṛṣṇa, that is spiritual energy. Now, the question is how the woods and stone, which is matter, becomes spiritual. Is not that the question?
We say one man is constructing big skyscraper building with woods and stones, we say this is materialism. But they can also challenge you that, "You are also interested in woods and stones and constructing a big church or temple. Why is your idea spiritualism?" Now, you can compare. This is spiritualism means in this stone and earth and woods you remember Kṛṣṇa, "I am constructing something for Kṛṣṇa." Therefore it is spiritualism.
So the conclusion is when we forget Kṛṣṇa, that is materialism. And when we constantly remember Kṛṣṇa, that is spiritualism. The materialist means they are thinking of sense gratification. All these big, big buildings were constructed in your country, Edinburgh. The idea was that, "We shall show something opulent that we are very great nation. We have got nice buildings, nice churches, nice roads." Puffed up. Everyone wants to be puffed up before his friends and relatives. So this is materialism.
But the same thing done for the satisfaction of Kṛṣṇa that, "We shall construct this temple for Kṛṣṇa's inhabitation. We shall construct this building for providing the devotees of Kṛṣṇa so that they may be able to chant Hare Kṛṣṇa mahā-mantra without any disturbance . . ." It appears the same thing, karma and bhakti, but bhakti is always in relation with Kṛṣṇa and karma is always in relation with sense gratification.
Therefore the things, the ingredients, is originally spiritual because it is Kṛṣṇa's energy. But ahaṁ mameti, when we try to impose our proprietorship, that is materialism. Materialism means forgetfulness of Kṛṣṇa. Otherwise, there is no materialism—everything is spiritual.
Pradyumna: "Kṛṣṇa is our most intimate master, friend, father or son, and object of conjugal love. Forgetting Kṛṣṇa, we have created so many objects of questions and answers, but none of them are able to give us complete satisfaction. All things but Kṛṣṇa give temporary satisfaction only, so if we are to have complete satisfaction we must take to the questions and answers about Kṛṣṇa. We cannot live for a moment without being questioned or without giving answers."
"Because the Śrīmad-Bhāgavatam deals with questions and answers that are related to Kṛṣṇa, we can derive the highest satisfaction only by reading and hearing this transcendental literature. One should learn the Śrīmad-Bhāgavatam and make an all-around solution to all the problems pertaining to social, political or religious matters. Śrīmad-Bhāgavatam and Kṛṣṇa are the sum total of all things."
Prabhupāda: Now let us discuss, question and answer, "How political situation can be improved by Kṛṣṇa consciousness?" Can anyone answer? Who will answer this question? Yes?
