Fark Between Easement aur Profit - Aise Kuch Bachche Kahan Hai?

Main to abhi tak TPA se jyada confused hoon. Hum kaise decide karte hain ki koi jagah par easement hai ya profit? To mere teachers aate hain ki easement mein owner ki permission ki zaroorat hoti hai, lekin profit mein zaroorat nahi. Lekin main to socha hoon kya yeh ek jaisa farq hai? Kya koi example hai jo yeh samajh aayega? Kuch real-life situation hoga jahaan hum easement vs profit ka difference kar sakte hain. Jaise kya, agar koi gadi park karke ja rahi hai aur hum use pass karne ke liye jama padte hain, isme kya hai - easement ya profit? Koi batao, please!
