damyanti,
As with everything else in the lifestyle 'Obedience training' has different means to differnt people. The level of agreed service and styles of the people involved. At the most basic level it involved the Dom/mie setting rules to be followed by their sub. The rules are learned by the sub and often reviewed by their Dom/mie. The review can be verbal or by preformance and review. As in anything praise for a job well done is expected in what ever form is in keeping with the relationship.
Corrections for incorrect actions, failure to follow rules or shy/hesitant behavior can be as simple as verbal correction and reinforcment of the rules to be followed. Repatition is the key to learning her as in all things. In stricter relationships the incorrect behavior often involves negative reinforcement. This can be stern looks, harsh words and raised vices or in more serious situations physcial correction.
What works for one sub may be completely incorrect for the next. For some a simple over the lap spanking brings tears and promises to be good. For others more sever punishment might be in line. Once you get to know a sub well you wil find there are often ways to correct that dont require spanking or flogging. If the sub said something incorrectyly or inappropriate try making them were a gag or simple ordering them not to speak again until allowed. Such actions can bring home the point as they have to live with the cost of their error and not dwell on how bad you treated them.
The best ideas are corrections that suit the transgressions. This works best once you actually know the sub and what affects them most. If you need ideas on specific situations im sure the creative people at this site can help with suggestions. <WG> I hope this has been more helpfulk than confusing.
