" The whole material world is full of hungry living beings. The hunger is not for good food, shelter or sense gratification. The hunger is for the spiritual atmosphere. Due to ignorance only they think that the world is dissatisfied because there is not sufficient food, shelter, defense and objects of sense gratification. This is called illusion. When the living being is hungry for spiritual satisfaction, he is misrepresented by material hunger. But the foolish leaders cannot see that even the people who are most sumptuously materially satisfied are still hungry. And what is their hunger and poverty? This hunger is actually for spiritual food, spiritual shelter, spiritual defense and spiritual sense gratification. These can be obtained in the association of the Supreme Spirit, Lord Śrī Kṛṣṇa, and therefore one who has them cannot be attracted by the so-called food, shelter, defense and sense gratification of the material world, even if they are relished by the denizens of the heavenly planets.
