Kṛṣṇa reveals the fundamental difference between the individual soul and the Supreme Lord. He explains that both He and Arjuna have passed through many, many births across time. However, Kṛṣṇa remembers every detail of every appearance, while Arjuna has forgotten his previous lives. The individual soul (jīva) forgets its past because its identity is tied to a temporary material body that dies and is replaced. This forgetfulness is a symptom of being under the influence of ‘māyā’. Kṛṣṇa, however, is the master of material energy and never loses His eternal consciousness. His memory is perfect because He never changes His spiritual identity. This verse establishes Kṛṣṇa’s omniscience. He is the constant witness of all history and all lives. While Arjuna is limited by the current moment, Kṛṣṇa sees the entire timeline of the universe simultaneously. This vast perspective is why Kṛṣṇa is the only one qualified to guide Arjuna through his current crisis.
