This is metaphorically 'twilighted' in the RGV as dhruva "pole star". From the vantage of the Northern Hemisphere of Earth, the pole star is apt because day or night it is always in the sky, hence constant, immutable and fixed, but not necessarily visible. The pole star appears not to move but the heavenly bodies revolve around it as though it is a fixed 'point' (Sanskrit: bindu). Just as the pole star is not truly fixed in the sky, the 'everlasting' aspect is not eternal, and should be understood as subject to the Catuṣkoṭi which is employed in the RGV. The 'essence', the 'element', the 'ratnagotra' must not be essentialized. Rather than the term 'eternal' or 'everlasting' which smacks of 'eternalism' (Pali: "sassatavada") anathemic to Buddhadharma, a continuum spontaneously 'self-emergent' (rang shar) is sound .
