BG Chap 7 - The mūḍhas who do not surrender to Kṛṣṇa
Even the learned do not surrender unto Kṛṣṇa even though one attains liberation doing so. The wise like Brahmā, Śiva, Nārada and others surrender unto Kṛṣṇa, but those who only think themselves wise like the philosophers, scientists and others, do not. Those who know the meaning of scripture but are evil and who misuse knowledge do not surrender to Kṛṣṇa. Four types of people are devoid of piety – the foolish, the lowest of mankind, those whose knowledge is stolen by illusion and the demoniac- and thus they never surrender to Kṛṣṇa.
The mūḍhas are those who are grossly foolish, like hardworking beasts of burden. Most often, those who work very hard day and night to clear the burden of self-created duties say that they have no time to hear of the immortality of the living being. To such mūḍhas, material gains, which are destructible, are life's all in all-despite the fact that the mūḍhas enjoy only a very small fraction of the fruit of labor. The fool equal to an animal is the person pursuing enjoyment thru his work. Those who are condemned by fate avoid the nectarean topics of Lord Acyuta and listen instead to the impious narrations of materialists. The mūḍhas’ intelligence are dulled by fruitive work and they think Viṣṇu is like Indra, attainable by pious actions and Viṣṇu is like the jīvas controlled by karma. Those who follow the path of karma think that God has a material body.
