According to J. Krishnamurti in "Individual and Self," the fundamental barrier to understanding the true nature of the individual lies in:
1
The inherent limitations of human intellect and the impossibility of transcending subjective experience.
2
The ingrained societal conditioning and the accumulation of knowledge and beliefs that create a false sense of "self."
3
The necessity of rigorous philosophical inquiry and disciplined meditation to gradually dismantle the ego.
4
The elusive and ever-changing nature of consciousness, making it impossible to grasp a stable sense of self.
