Sāṅkhya Enumeration of Tattvas, Distinction of Puruṣa–Prakṛti, and the Mechanics of Birth and Death
निषेकगर्भजन्मानि बाल्यकौमारयौवनम् । वयोमध्यं जरा मृत्युरित्यवस्थास्तनोर्नव ॥ ४७ ॥
niṣeka-garbha-janmāni bālya-kaumāra-yauvanam vayo-madhyaṁ jarā mṛtyur ity avasthās tanor nava
受胎、胎内の成長、誕生、乳児期、幼年期、青年期、中年期、老年期、そして死—これらが身体の九つの段階である。
In 11.22.47, Lord Kṛṣṇa explains that the body undergoes nine successive stages—conception through death—showing its temporary, ever-changing nature.
Kṛṣṇa teaches Uddhava to cultivate clear detachment and self-knowledge by seeing the body as a changing condition, distinct from the eternal ātmā, thereby strengthening steady devotion.
By remembering that the body inevitably changes from youth to old age and death, one can reduce anxiety and pride, prioritize spiritual practice, and invest life in bhakti rather than temporary bodily identity.
