The World and Five Aggregates of Clinging As I've heard, the "world" referred by Buddha (mentioned in the Loka Sutta and in Samyutta Nikaya - 4 -> LokaSamudaya Sutta) is the same as "Five Aggregates of Clinging" (Five-Updana-Skandas).

That's why the world in one's mind is different than the other's world.

It would be great if anyone can explain this further.
There is no such thing as "five aggregates of clinging". The aggregates are things clung to therefore the meaning is "five aggregates clung to". 

As for the word "loka" ("world"), there are many suttas that do not refer to this as the "physical world". The Loka Sutta refers to the "world" in the mind that is produced by egoism, such as "my family", "my country", "my planet earth", "my favourite television", "my life", "my career", "my purpose", etc. 

Or other times, the suttas refer to "the world" is a predominant mental state; such as "jhana" as "the world exclusively of pleasant feelings" (MN 79). 

The "world in the mind" is different for different individuals because each individual views &amp; conceives (creates; manufacturers) the world differently. For some, the world is a place of "pleasure" or a place of "sacredness" or "produced by god" or something with a "plan for humanity". For others, the world is an "illusion", "unsatisfactory", "meaningless" and "worthless". 

For example, right now, there are powerful people ("the gods") planning the future of the world to benefit themselves &amp; their future generations. Where as there are also other people who have given up on the world, merely waiting for what they regard as a stupid world &amp; life to end &amp; pass. 

For each individual mind, the conception of "the world" is different. These conceptions are endless in number &amp; variety.
