Can I take enema even when I am not fasting?

Yes, absolutely! 

We recommend that once you start following the Satvic lifestyle, take enema once every day for 21 days (take only 300-500 ml of water at a time). This is to ensure a master cleanse of the intestines to get rid of all the waste that has accumulated inside over a lifetime of wrong food and lifestyle. This should be only a one-time cleanse. 

After 21 days, do not take it everyday. Take it only once a week (to ensure that if any toxins start getting accumulated, they are immediately flushed out of the body). Also, if you are suffering from an acute disease or detox symptom (cold, cough, fever, headache, vomiting, diarrhea, inflammation), take enema twice every day to aid the praan shakti in its cleansing work.
