What exactly was the difference between Alara Kalama & uddaka rāmaputta teachings? Correct me if I am wrong.

Siddharth went to Alara Kalama, who told him to focus on his breath in order to get rid of Feelings, (Buddha achieved Alara Kalama level in 2 months), Now he told his teacher that when he is in meditation, everything is fine but on coming to ordinary state, Negative &amp; positive Feelings again came to him.

Now Alara Kalama told him to go to uddaka rāmaputta, What did Siddharth learn under uddaka rāmaputta ?

Above information is seen in an indian television show "Buddha"
I wanna know what happened in real ?
The two teachers are in the Ariyapariyesana Sutta.

Alara Kalama taught to focus on 'nothingness' and Uddaka Ramaputta taught to enter the 'dimension of neither perception nor non-perception'.

Both meditations are only mental stillness &amp; quiet and do not uproot the causes of suffering. The the 'dimension of neither perception nor non-perception' is very close to unconsciousness. They can only bring temporary peace, which is why the Buddha rejected them. They are not freedom. The Buddha discovered true freedom is having no craving, no attachment and no self.
