It clarifies that cosmic time is not uniform everywhere: some realms do not run by the standard four-yuga cycle, implying different temporal laws even across creation’s domains, though it does not directly describe pralaya events.
By stating that time may resemble Tretā-yuga in certain realms, it reinforces the idea that dharma is calibrated to the age; kings and householders should follow the appropriate yuga-based standards of righteousness, discipline, and sacrifice as taught in Purāṇic ethics.
No explicit Vāstu or temple rule is stated; the practical ritual takeaway is that rites and dharma can be prescribed according to the prevailing yuga-quality (here, Tretā-like), which traditionally emphasizes more formal sacrificial and disciplined observances.
