The word adas 'that' is called gati when in composition with a verb and not implying a direction to another.,
The word upadesa means a direction to another. When a person cogitates within himself and does not address another, that is anupadesa. That is when it is not a demonstrative pronoun. As अदः कृत्य, अदः कृतम् and यददः करोति when used as a demonstrative pronoun we have अदः कृत्वा काण्डं गतः.,
