Śrāddha-kalpa: Amarakantaka–Tīrtha-Māhātmya and Akṣaya Pitṛ-Tarpaṇa
ध्यानं तीर्थं परं तस्माद्ब्रह्मतीर्थं सनातनम् / उपवासात्परं ध्यानमिन्द्रियाणां निवर्त्तनम्
dhyānaṃ tīrthaṃ paraṃ tasmādbrahmatīrthaṃ sanātanam / upavāsātparaṃ dhyānamindriyāṇāṃ nivarttanam
Therefore meditation is the supreme tīrtha—the eternal Brahma-tīrtha. Higher than fasting is meditation, the withdrawal of the senses.
