शकुन्तलाप्रत्याख्यानम् (गद्य) — संस्कृत STD 11 Science — Question

आत्मगतम् means self-addressing, a kind of dialogue spoken on the stage. This type of dialogues are not heard by other characters on the stage and that's why they are called अश्राव्यं (unhearable). To present their views to the viewers, the characters come to the front side of the stage and speak their dialogue. Therefore it is said that : अश्राव्यं स्वगतं - आत्मगतं स्मृतम्।
