Why is Bernard unable to feel the oneness with his group in the novel Brave New World?

Bernard struggles to feel a sense of oneness with his group in "Brave New World" because he is highly individualistic and has personal insecurities, which isolate him from the conformist society around him. His nonconformity and questioning of societal norms create a barrier between him and his peers, preventing him from fully integrating into the group mentality promoted by the World State.
