Devotee: If someone is doing some service which involves business, is he thinking of Kṛṣṇa when he's thinking of that service?
Prabhupāda: Yes, if he's doing for Kṛṣṇa, he must be thinking of Kṛṣṇa. Just like somebody works in business or factory for the wife and children, he always thinks of them. Although he's working in the factory or business, he's thinking of the welfare of his wife, children, family. Similarly, if you actually work for Kṛṣṇa, you'll think of Kṛṣṇa.
