1.3.8.62

liṃgameva paraṃ jñānaṃ liṃgameva paraṃ tapaḥ..
liṃgameva paro dharmo liṃgameva parā gatiḥ..
tasmālliṃgātparataraṃ yacca kiṃcinna vidyate.. 10.62 ..

“The liṅga alone is the supreme knowledge; the liṅga alone is the supreme austerity; / the liṅga alone is the supreme dharma; the liṅga alone is the supreme goal. / There is nothing whatever higher than that liṅga.”
