Matsya Purana — The Legend of Acchodā: Pitṛloka
नाम्ना सत्यवती लोके पितृलोके तथाष्टका आयुरारोग्यदा नित्यं सर्वकामफलप्रदा //
nāmnā satyavatī loke pitṛloke tathāṣṭakā āyurārogyadā nityaṃ sarvakāmaphalapradā //
In the human world she is known as Satyavatī, and in the world of the Ancestors she is called Aṣṭakā. She ever bestows long life and freedom from disease, and grants the fruits of all desired aims.
This verse does not address Pralaya; it focuses on Pitṛloka and the spiritual efficacy of an Aṣṭakā-related observance/personification that grants longevity, health, and desired results.
It reinforces the householder’s (and ruler’s) duty to uphold Pitṛ-karmas such as Aṣṭakā/Śrāddha traditions, teaching that proper ancestral observances sustain wellbeing (āyuḥ, ārogya) and support legitimate aspirations (kāmas) in worldly life.
The significance is ritual rather than architectural: Aṣṭakā is presented as a Pitṛloka-linked observance/name that yields tangible fruits—health, long life, and fulfillment of aims—highlighting the Matsya Purana’s emphasis on the power of ancestral rites.
