Bhagavad Gita 1.12
Then, to enliven his spirits, the brave Grandfather Bheeshma, the eldest of the Kuru clan, blew his conch, its sound resembling that of a lion's roar.
तस्य संजनयन्हर्षं कुरुवृद्धः पितामहः।
सिंहनादं विनद्योच्चैः शङ्खं दध्मौ प्रतापवान्॥tasya saṃjanayanharṣaṃ kuruvṛddhaḥ pitāmahaḥ|
siṃhanādaṃ vinadyoccaiḥ śaṅkhaṃ dadhmau pratāpavān||
