Faith and belief in religion is a matter of pure personal conviction. The religion [I rather call it ones faith and belief] is again a relative term because there are various degrees even within the same faith. Hence it is an un-necessary hue and cry on Mr. Bush visiting or omitting to visit the Mahatma's samadhi.
However, the Mahatma is and will continue to remain revered for each and every Indian and also any human whether his samadhi is visited or not.
Thank you for your patient reading of my feedback. Regards
