Hare Krishna ,
All glories to Srila Prabhupada ,
Once SP said that we should keep ekadashi according to our capacity , it does not meant not to keep it , but with respect to diet ..
For Past 10 Days i was giving exam ,today was also my exam , tommorow is ekadashi , should i keep it with force without water , which is outside my capacity or like normal ekadashi ..
1 more question on ekadashi we do not offer Krsna any thing that is made of grain , what to offer him on Nirjala Edadashi ..
