Bhagavatapurana 3.19.38

3.19.38

etan mahā-puṇyam alaṃ pavitraṃ dhanyaṃ yaśasyaṃ padam āyur-āśiṣām /
prāṇendriyāṇāṃ yudhi śaurya-vardhanaṃ nārāyaṇo 'nte gatir aṅga śṛṇvatām //

38. This is a highly sacred story which confers great merit, happiness, reputation, long life and many other blessings on the hearer, which is the source of the (strength) of life and senses and which promotes heroic spirit on the battlefield; and to those that listen to it Narayana will be the resort at the end.
