Nectar Drops from Srila Prabhupada
"Materialist does not mean something extraordinary personality. One who does not know about Kṛṣṇa, he is materialist. And one who makes progress in the science of Kṛṣṇa under regulation and under principles, they are called spiritualist. So materialist, the disease is that harāv abhaktasya kuto mahad-guṇā mano-rathena asati dhāvato bahiḥ (SB 5.18.12). Unless we take to Kṛṣṇa consciousness fully, we shall hover over the mental plane. You will find so many philosophers, doctors of philosophy, they can go on speculating, mental plane, manaḥ, but actually they are asat. Their activities will be seen in materialistic. There is no spiritualistic realization. So more or less degree, this material conception is everywhere."
