Śrāddha-kalpa: Amarakantaka–Tīrtha-Māhātmya and Akṣaya Pitṛ-Tarpaṇa
अल्पेन तपसा सिद्धिं गमिष्यन्ति न संशयः / सकृदेवार्चितास्तत्र स्वर्गमामरकण्टके
alpena tapasā siddhiṃ gamiṣyanti na saṃśayaḥ / sakṛdevārcitāstatra svargamāmarakaṇṭake
With but little austerity they will attain accomplishment—of this there is no doubt. At Amarakantaka, even a single act of worship offered there leads to heaven.
