What does Ishita mean?
From the Sanskrit ईशिता (īśitā), 'superiority, supremacy, lordship' — one of the eight siddhis (mystic powers) in yogic tradition. Commonly rendered 'one who desires to rule' or 'preeminent'.
What does Vedika mean?
From the Sanskrit वेदिका (vedikā), 'a sacrificial altar, raised platform', and in architecture the railing enclosing a sacred space. The popular 'knowledgeable woman' gloss (via veda, 'knowledge') is a folk etymology, not the dictionary sense.
