Acharya Prashant explains that the concept of the 'Day of Judgment' or 'Qayamat' found in various religions is a pedagogical method designed to awaken those who are oblivious to the consequences of their actions. It serves as a warning to individuals who believe they can commit sins and escape accountability. By suggesting that even the dead will be raised from their graves for judgment, religions ensure that people do not use death as an excuse to live unethically. For a conscious person, such threats are unnecessary, but for those living in ignorance, the language of fear is often the only effective tool for guidance.
