Skanda Purana — Nagara Khanda, Shloka 15
अग्निष्टोमादयो यज्ञा ये प्रोक्ताः प्राक्स्वयंभुवा । अन्यदेहांतरे स्वर्गः प्राप्यते तैः कृतैर्नृप
agniṣṭomādayo yajñā ye proktāḥ prāksvayaṃbhuvā | anyadehāṃtare svargaḥ prāpyate taiḥ kṛtairnṛpa
হে রাজন! স্বয়ম্ভূ ব্রহ্মা প্রাচীনকালে যে অগ্নিষ্টোমাদি যজ্ঞ বলেছেন, সেগুলি করলে স্বর্গ লাভ হয়; কিন্তু তা দেহান্তরে প্রবেশের পরেই (মৃত্যুর পরে) প্রাপ্ত হয়।

Listener: Triśaṅku
Scene: Vasiṣṭha enumerates Vedic sacrifices—Agniṣṭoma foremost—while explaining that their heaven is reached only after leaving the present body.
FAQs
Vedic sacrifices can grant heavenly merit, but their fruition is generally post-mortem; the verse contrasts delayed ritual reward with the desire for immediate attainment.
This verse itself speaks generally of yajña and svarga; the broader Tīrthamāhātmya context frames the teaching within sacred-geography praise, but no single tīrtha is named in this line.
Performance of Vedic sacrifices such as the Agniṣṭoma is referenced as the means to attain svarga.
