Greetings everyone! I am sorry to ask this question but I had some curiosity in my mind so I am asking it. This time I wish to ask that why Buddhas only take birth in higher caste and not in lower caste? The Lalitavistara sutra says that Buddha takes birth in a central land and only in higher caste. I know that the Buddha didn’t discriminate lower castes and ordained them equally like others. For example, the low caste scavenger Sunita was ordained by the Buddha. Similarly Upali, a barber, was ordained by the Buddha before Sakyans, so that the latter would pay homage to him as he would be senior to them. In the Assalayana Sutta, the Buddha debates with a Brahmin and disputes the claim that Brahmins are the highest caste, born from the mouth of Brahma. In my opinion, the Buddha was the greatest man ever born ever in this Universe. But still I have some doubts about the authenticity of some sutras. I am pasting a quote from Lalitavistara Sutra below where the Buddha says that a Buddha is not born into a lower caste despite the fact that in some Jatakas, the Boddhisatta is born in some lower castes many times.
"And why, monks, did the Bodhisattva behold the country of his birth? Because a
bodhisattva is not born in outlying lands where people are as stupid as sheep, with
dull faculties, ignorant, and incapable of distinguishing right from wrong. Rather a
bodhisattva is born in a central land.
And why, monks, did the Bodhisattva behold the family of his birth? Because a
bodhisattva is not born into an inferior family, like a family of outcastes, flute makers, cartwrights, or servants. A bodhisattva is only born into one of two families—a
priestly family or a family of the ruling class. When the priestly families are dominant in the world, the bodhisattva is born into a priestly family. When the rulingclass families are dominant in the world, the bodhisattva is born into a ruling-class
family. Thus, monks, at this time the ruling-class families were dominant in the
world, so bodhisattvas were born into such families. " (Lalitavistara Sutra)
