The Gita seems to teach that varna (often translated as caste) is determined by birth (A THREAD).

Gita 18:41-48: (1/n)

In summary, people are divided into varnas based on their gunas (qualities) by birth.
It lists the various duties of each varna. V. 46-48 say people must do their duties and must not let go of them even if they are bad at it. That sounds like varnas are meant to be rigid. (2/n)

I request Hindus to show passages FROM THE GITA that say something like “people can change their varna” or “everyone is born a Shudra”, I looked online and couldn’t find any.
Gita 9:32,33 says something similar: (3/n)

This is the translation of Adi Shankara’s commentary. He considered women, Vaishyas and Shudras to be examples of those who were of a “sinful birth”. He is one of the most important scholars of Hinduism (if not the most important) and is credited with unifying (4/n)

the main thoughts of “Hinduism”.
Even if you say there should be a comma after “sinful birth” instead of a hyphen, the next verse clearly says Brahmins are obviously superior to this other group of people (those of sinful birth, women, Vaishyas and Shudras). (5/n)

In fact, in his commentary (Gita 18:41), he says Shudras are barred from studying the Vedas. (6/n)

Swami Swarupananda was a direct disciple of Swami Vivekananda and the first president of the Advaita Ashrama. He goes further and calls them of “inferior birth”:
In his commentary on Gita 9:32, he explains: (7/n)

"Of inferior birth . . . Sudras—Because by birth, the Vaishyas are engaged only in agriculture &c., and the women and Sudras are debarred from the study of the Vedas." Women are also debarred from studying the vedas.

Also, Arjuna says in the Gita that women who intermingle with people of other castes are impious, corrupt and even evil, calls them the destroyers of families and says their actions will result in their whole family going to hell. (9/n)

Let me know if Krishna opposed these thoughts (Gita 1:40-46). (10/n)

Gita 3:35 "Better one's own duty, though devoid of
merit, than the duty of another well discharged.
Better is death in one's own duty ; the duty of
another is productive of danger. " Shudras who don't serve the other castes (which is their duty, Gita 18:44) go to hell! (11/n)
