Bhishma said Do you, O son, always behave towards your younger brothers as their eldest brother should. You are always the eldest of all these your brothers. You should always treat your younger brothers in the way in which a preceptor treats his disciples.
भीष्म उवाच ज्येष्ठवत् तात वर्तस्व ज्येष्ठोऽसि सततं भवान्। गुरोर्गरीयसी वृत्तिर्या च शिष्यस्य भारत॥
