Section 3 of Indian Evidence Act: Hearsay Evidence mein kya hai?

I am lagging behind, aap log ko kya pata? Main to Evidence Act aur BSA ko padh raha hoon. Hearsay evidence ke bare mein socha, aur pata chala ki yeh bahut hi important hai, lekin main samjh nahi paya. Section 3 ke anusaar hearsay evidence hai jab koi individual kisi third person ki baat ko apne aap par lagaata hai, aur us third person ne baat kahi thi. Lekin yeh toh sach hai, phir bhi yeh hearsay hai kya? Main toh confused hoon. Aap logon se meri madad karen. Ye toh question hai AILET ke paper mein aata hai.
