In this hand any two low cards (that aren't on the board) beats you. That is, any combination of A,4,6 and 7.

A4, A6, A7, 46, 47, 67.

To read low, some people turn it around and read backwards. For example, on this board you have 85321 (A=1). Any number below this beats you, for example 76532 beats you. I find this method confusing and brain dead.

Basically, you think of it like this. If you have two unique cards in your hand that aren't counterfeited, then anyone with two cards lower than your highest card beats you. For example, if you have A4 on a 567 board, A2, A3 and 23 beat you.

If you are counterfeited, anyone with two cards lower than the highest card on the board has you beat. For example, on a 2358 board, any combination of A,4,6,7 has you beat.

** Counterfeited = a card in your hand is duplicated on the board, for example A2 on a 2358 board, your 2 is "counterfeited".
