Master Lin gives the dantien as behind the navel. Other Qigong systems that I have seen give the dantien as 2inches below the navel, as do the Japanese with the Hara.

Why is this?

I practise other energy work as well as SFQ and can feel my energy at that point about 2 inches below the navel.

Will it make any difference to my SFQ practise if I use 2 inches below the navel which I am used to.

Or can I have multiple dantien? Why not?
