Is it true as stated in Manu Smriti that a Brahmin can compel a Sudra to be servile or it is an interpolation?
"BG 4.1: The Supreme Lord Shree Krishna said: I taught this eternal science of Yog to the Sun God, Vivasvan, who passed it on to Manu; and Manu, in turn, instructed it to Ikshvaku"
"O subduer of enemies, the saintly kings thus received this science of Yog in a continuous tradition. But with the long passage of time, it was lost to the world." BG Ch4 verse 2
