We end the Futhark with Dagaz (ᛞ) because we believe that after one realizes the true Self, represented by Othala (ᛟ), one can then “break the cycle” of saṃsāra, like the breaking of dawn on a new day. 

This process of enlightenment is represented by Dagaz.

In reality, whether you end with Othala or Dagaz, one can theoretically come to the same conclusions either way. 

These choices are not meant to be dogmatic, but philosophical. Make the decision on your own, based on research and practice.
