What is the best way to cook brown rice? After soaking can we pressure cook it for 2-3 whistles?

The best way to cook brown rice is to soak it overnight and then cook it in a stainless steel vessel with a lid. 

We do not suggest using pressure cookers in the Satvic lifestyle (unless using it for rajma or chana) as it uses an extremely high temperature, of around 220 degree celcius. As a result, all the vital nutrients in the food get destroyed.
