Radha soami, we should obey atleast three persons in our life i.e our parents and our master/guru because they alwawys give right advice to us.

Sorry! Advice of anyone cannot and should not be taken to be right without application of one's mind.

What if there is some vital difference/dispute about advice given by parents and that given by GURU/Master? e.g.Parents advice to spare time for meditation only after sparing full time for upkeep of kids and other duties, whereas GURU/MASTER advices to spare atleast two and half hours time daily for meditation by giving over riding priority to it even if it comes in way of family affairs or official duties.

We should follow the orders of parents first as they are one who have given birth to us and knows better for us then any one else on this earth.

Yes! Status of parents' advice is much above the status of GURU's teachings, more so because parents are one's over all teachers (including spirtuality)as well as source to bringing one to this beautiful world.
