Section 123 of the Indian Evidence Act: Lagta hai kya?

Main aaj confuse ho gaya, kyun ki Section 123 ke baare mein. Sabse pehle, Section 123 kya karta hai? Isse pata lagta hai ki jo alag-alag vakiyein (statements) ek aur uske sath-sath ki hai, unhein judge ko ek hi baar parhe ja sakte hai, lekin ek hi vakt. Thodi si difficult hai, lekin main try karunga. Problem yeh hai, maine kadi baar padha hai ki judge ko kaise ek aur uske sath-sath ki vakiyon ko ek hi baar parne se wapas unhein alag karne padta hai. Lagta hai kya, yeh Section 123 wapas ek baar padhna zaroori hai. Koi idea hai?
