All creatures within the earth fulfill the necessities required for human beings, and all living entities can be taken out of the earth by the proper means. As suggested by the planet earth, and accepted and initiated by King Pṛthu, whatever is taken from the earth — either from the mines, from the surface of the globe or from the atmosphere — should always be considered the property of the Supreme Personality of Godhead and should be used for Yajña, Lord Viṣṇu.
