नाभ्येति कारणं कार्य न कार्य कारणं तथा । कार्याणां तूपकरणे कालो भवति हेतुमान्,न तो कारण कार्यमें प्रवेश करता है और न कार्य कारणमें। कार्य करते समय काल ही उनकी सिद्धि और असिद्धिमें हेतु होता है
nābhyeti kāraṇaṁ kāryaṁ na kāryaṁ kāraṇaṁ tathā | kāryāṇāṁ tūpakaraṇe kālo bhavati hetumān, na tu kāraṇaṁ kāryam |
भीष्म उवाच—न कारणं कार्ये प्रविशति, न च कार्यं कारणे तथा। कर्मणां तु प्रवृत्तौ काल एव हेतुमान् भवति, सिद्ध्यसिद्ध्योर्निर्णायकः।
भीष्म उवाच
The verse distinguishes cause and effect as conceptually separate and emphasizes that, in practical outcomes, Time (kāla) functions as the decisive factor behind success or failure. It cautions against assuming a simple, direct ‘cause merges into effect’ model and highlights temporal conditions as crucial.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and right understanding. Here he offers a philosophical clarification about causality and the role of Time in the fruition of actions, as part of broader ethical and metaphysical counsel after the war.
