The shlok shown on this show where a priest said it meant - Mahapurush's mouth formed the Brahmana, His arms made Kshatriya, His two thighs the Vaishyas and from His feet the Shudras. This shlok is highly misinterpreted, misused and misjudged. Just yesterday in Upanishad Ganga they explained what this meant. The episode in not uploaded yet but once it is, I will post the link. Please watch it to understand the real meaning
Suppressors distort bits from ved and make a mess in society. They will create a havoc if they are touched by low-caste people but what about untouchability when they rape a low-caste girl/woman, as seen in many reported incidents. It clearly shows that they practice what suits them. One of the ladies in the show said she read in scriptures that low-caste people should be treated in a certain way. I am not sure what she read. Ved and God will never ask you to differentiate between people in such fashion. This is all created by Humans.
Firstly BRAHMIN, KSHATRIYA, VAISHYA & SHUDRA are Varn Vyavastha but since there is no word equivalent to in English its got translated as Caste. That is not correct. Its clearly said that unless like for a healthy human body Mouth, Arms, Thighs and Feet need to work in tandem, similarly a Sabhya Samaj can function properly only when these 4 Varn work and live in sync.
