Acharya Prashant explains that the physical body is not an obstacle in the spiritual journey; rather, it is the ego that uses the body to create disturbances. Just as a hand or a knife is not inherently violent but is used by a person for violence, the ego utilizes the body to manifest symptoms like sleepiness, hunger, or physical pain when it feels its false beliefs are being threatened. He notes that if a spiritual process were ineffective, the ego would remain calm and indifferent. However, when a spiritual session accurately targets and wounds the ego, the ego reacts by creating physical discomforts or distractions. Acharya Prashant emphasizes that experiencing such bodily obstacles during spiritual discourse is actually a sign of progress, indicating that the teaching is effectively hitting its mark and causing the ego to struggle in self-defense.
