I found a Rehatnama today, which you may have seen before. It is strongly saying to learn the wonderful language of Gurmukhi, so we can read GurbaNee paath and teach others too.
O'Brother The Gurmukhee Akhars that exist,
Gursikhs Keep on learning from Gursikhs.
Additional education that may exist, they also receive from others.
Rehatnama Bhai Desa Singh jee
