The verse underscores that true teaching about dharma and spiritual discipline is validated by the testimony of realized sages and by the cosmic order itself: those who practise steady tapas are supported by higher authority, symbolized by the Sun as an ever-present witness.
Yājñavalkya is affirming a doctrine by appealing to two sources of authority: (1) the great seers who have attained Brahmaloka and (2) Āditya, the Sun, who is invoked as a universal witness that ‘proclaims’ or illuminates the truth of the teaching for steadfast ascetics.
