From Bhoja's comment on YS III 49 'Velocity of mind' (manojavitva) means attainment of rapid motion by the body like that of the mind ([probably translator's addition:]that is, the ascetic can move his body from one place to another as quick as the mind).
Beginning of the original comment by Bhoja (hyphens added): sharIrasya manovad anuttama-gati-lAbho mano-javitvam शरीरस्य मनोवदनुत्तमगतिलाभो मनोजवित्वम् That seems to be possible only by utilizing quantum entanglement?
