Wakai confusion: Section 23 of Indian Contract Act

Bhai, mujhe lagta hai ki Section 23 kaa dhundh hai. Kya main hi kuchh samjh nahi pa raha? Is Section mein kaha gaya hai ki kisi bhi contract mein jo ek adhikar hai ki voh kisi vyaavastha ko pura karna ho sakta hai, vah ek conditional promise hai. Lekin, yehi Section ke paas kaha gaya hai ki conditional promises kisi khaas sthiti par aadhaarit hoti hain. Kya yehi kaahein hai, kya kuchh aur hai? Agar conditional promise kisi sthiti par aadhaarit hai, toh yeh to pura nahi karna hi hoga.
