Tīrtha-yātrā: Phalaśruti and Sacred Geography from Lohitya to Prayāga
Pulastya’s Instruction
स्वर्गद्वारं ततो गच्छेन्नियतो नियताशन: । स्वर्गलोकमवाप्रोति ब्रह्मलोक॑ च गच्छति,तदनन्तर नियमपरायण हो नियमित भोजन करते हुए स्वर्गद्वारको जाय। उस तीर्थके सेवनसे मनुष्य स्वर्गलोक पाता और ब्रह्मलोकमें जाता है
svargadvāraṁ tato gacchen niyato niyatāśanaḥ | svargalokam avāpnoti brahmalokaṁ ca gacchati ||
Thereafter, disciplined and restrained in diet, one should proceed to the ‘Gate of Heaven’. By resorting to that sacred ford, a person attains the heavenly world and also reaches the world of Brahmā (Brahmaloka).
घुलस्त्य उवाच
The verse teaches that disciplined conduct—especially restraint in food and regulated living—combined with reverent approach to a sacred tīrtha is presented as a dharmic path that yields elevated post-mortem destinations (Svarga and even Brahmaloka).
In the context of Vana Parva’s tīrtha-mahātmya passages, the speaker is describing the prescribed practice for a pilgrim: after certain observances, one should go to the place called Svargadvāra; the text then states the spiritual reward of visiting/serving that tīrtha—attainment of Svargaloka and Brahmaloka.
