Why suthak effects on people for different days in defferent region or cast? I did read THIS ANSWER and came to know about suthak. But from the answer and also from the comment section of this answer I came to know that Suthak apply for different number of days in different religion and cast! Why is that...?
First of all who decides days of suthak? Means, suthak will be applied for that many days, this is decided by whom? And why different days in different casts?
And also what will happen if we don't care about suthak and just follow our life's work by ignoring suthak's time?
