Step 1: Definition of Lokas.
Hindu cosmology posits the universe is comprised of multiple realms known as Lokas.
These Lokas are categorized as Ūrdhvalokas (upper realms) and Adholokas (lower realms).
Step 2: Identification of Swargaloka (A).
Swargaloka, Indra's heavenly abode, is populated by deities and celestial beings.
It is classified as an Ūrdhvaloka.
Step 3: Identification of Satyaloka (D).
Satyaloka, also termed Brahmaloka, is the supreme spiritual plane, the dwelling of Lord Brahmā.
This realm is also an Ūrdhvaloka.
Step 4: Exclusion of Other Realms.
- Rasatala (B): Classified as an Adholoka (lower realm).
- Pātāla (C): Also categorized as a lower realm, not an Ūrdhvaloka.
Step 5: Conclusion.
Consequently, the Brahmapurāṇa identifies Swargaloka and Satyaloka as the two Ūrdhvalokas.
