Hi Am keeping 9 weeks sai vrat. This is my 4th Thursday. The problem is in my house after periods we have to take head bath on 4th and 5th day and then oil bath on 6th day or 7thday and then only we can lit Diya for god or do any other poojas for god. Before taking oil bath we are not supposed to do any poojas for god. Today is my 6th day but today being amavasai I can not take head bath. My friend says for sai there is no strict rules as to periods and so I can keep fasting. But am a little skeptical. Can I keep fasting for sai today without taking head bath or should I skip this week. Pls can someone advice.
