These are four divisions: brahmana, ksatriya, vaisya, sudra. Sudra means laborer class, but they are also obedient to the other three classes. And less than that, they have been described as candalas, pancamas, or untouchable as you say. But for us, Krsna consciousness movement, there is no such distinction. Anyone can become Krsna conscious.

Yogeśvara:

cātur-varṇyaṁ mayā sṛṣṭaṁ

guṇa-karma-vibhāgaśaḥ

tasya kartāram api māṁ

viddhy akartāram avyayam

(BG 4.13)

"According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me." (translates)

Swiss man (1): But there are the outcastes, and they have . . .

Yogeśvara: Do you mean the untouchables?

Swiss man (1): Untouchables.

Prabhupāda: Outcaste means those who are less than the śūdras. They are called pañcamas. These are four divisions: brāhmin, kṣatriya, vaiśya, śūdra. Śūdra means laborer class, but they are also obedient to the other three classes. And less than that, they have been described as caṇḍālas, pañcamas, or untouchable as you say. But for us, Kṛṣṇa consciousness movement, there is no such distinction. Anyone can become Kṛṣṇa conscious. The pañcamas, the fifth-class men, are called caṇḍālas. Caṇḍāla means untouchable. So they are also many: kirāta-hūṇāndhra-pulinda-pulkaśā ābhīra-śumbhā yavanāḥ khasādayaḥ (SB 2.4.18). So Kṛṣṇa says, māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ (BG 9.32). There is . . . māṁ hi pārtha vyapāśritya.
