Gyani ji I've been following this series with much interest. I've printed all the relevant pages from The Sikh Bulletin and review them often - Dr Dhillon has packed each article with so much information.
To have them all in a booklet form would be just lovely and wonderfully generous seva from your family.
Please convey my deepest thanks to your brother (I believe) for his wonderful contribution to understanding Guru Nanak Sahib Ji's profound Japji Sahib.
