dear renukaji,
since you are a doctor by profession (as I suppose from your example) about 10 years back we were having only MBBS doctors., People used to go to them for medical checkup and they used to diagonise problem and give treatment. But science has grown so much that every part of our body has a specialised doctor who more depends on lab results. In the same way inBharath we have guides specialised in many ways to take us to mukthi marga whereas in other parts of world.they are just as with mbbs doctor. Here unityof humanity is not in question. Scope for upliftment was the point raised by e and I stick to the same.
