Question: If the microphone is composed of Kṛṣṇa's eight energies, why not the factory Kṛṣṇa's energy too?
Prabhupāda: Yes, everything is Kṛṣṇa's energy, but when it is not used for Kṛṣṇa's purpose, it is material. In the factory they manufacture things, but the products or the profit is enjoyed for sense enjoyment. If it is used for Kṛṣṇa's purpose, then it is spiritual.
