my owner has had me personally used mantras and other meditation techniques like tantra to help with my disipline and conditioning for a variety of things, (not all of them bdsm related).
Focus on His desires and intentions to bring my submission to his will to the forefront has and is a primary consern with regards to disipline in my relationship with my owner,, he has me under his will so to speak at all times, (even in here) sometimes its a more structured enviroment, such as, 0500 awake and clean house make bed etc, then prepare breakfast, then awake master in appropriate fashion, kegal excersies etc etc, like a schedule,
in other ways its much more circumstancial, depending on the situation, i ask myself what He would wish for me to do etc and in many instances something ive eaither invented myself to please him or anticipated he would desire has become incorperated into the realm of my submission ,
He has used a wide variety of disipline building excersises from cr(orgasm control/ no mastubation restriction etc) to dressing apropriately to his wishes, positional excersises, assigned behavoral tasks, preforming certian activites such as dance classess, even to being under the modality of the she quadruped and unable to verbally speak etc,
He has allways told me that such given tasks are not punishments because in our type of D/s relationship punishment is ussually swift and very direct.
over the years ive actually come to see the hidden wisdom within many of them as training to improve my submission to his will, especially ones i used to find uncomfortable at first such as remaining in an Ushiro Takatekote (arm box tie) wilst preforming certian tasks around the house etc etc
Reading and studying, eating what i am fed, (i love to be fed by hand) going to school, the gym, shoping etc etc, all become part of his dominion over me, all of them make up the love and freedom of my submission to his disipline ,his will

hopefully you and stripey can garner something to use for your own relationship from the above Sir, my owner and i are allways happy to help or give ideas, though admittably it would help to know what sorts of things you allready have her doing for you as disipline building excersises etc,
