Daas-san should try some of the "spiritual" teachers I know. After 3-4 sessions, he'll probably long for the more non-spiritual lectures.
I am currently ( and has been for 6 months ) treading neck-deep in spiritual aikido, and truly, truly wish I could train some additional physical-only aikido, somewhere.
Spiritual training should go in hand with the technical, or else it will encourage growth of many unpleasant human characteristics.
Which is probably one of aikido's worst shortcomings.
