Where can I get Buddha's teachings of the Dharma practice?
...without things that I don't need, especially without the idea that the purpose of Buddhist practice is to achieve enlightenment...


If we walk the path to the higher goal, the lower goals will be fulfilled along the way.


  ...the reason for me to practice is to reduce my suffering in this life...


Sooner or later, we'll realize that the only way to reduce our suffering in this life, is to help reduce the suffering of others. To have the strength to do it, we'll need very strong motivations.


  For example, the happier I am, the harder and more effectively I work...


There is nothing wrong in using the teachings to achieve mundane goals. However, this achievements are only temporary, and if we are not able to see this, they will only lead to more suffering.



Our ultimate purpose is using the practices to liberate ourselves of all relative conditionings, not only to improve them.
