See if you can find the vaaks where modern Punjabi uses the same word as is found in Sri Guru Granth Sahib, or in Dasam Granth
ਵਿਚੇ ਧਰਤੀ ਵਿਚੇ ਪਾਣੀ ਵਿਚਿ ਕਾਸਟ ਅਗਨਿ ਧਰੀਜੈ ॥
vichae dhharathee vichae paanee vich kaasatt agan dhhareejai ||
Water is locked up in the earth, and fire is locked up in wood.
ਬਕਰੀ ਸਿੰਘੁ ਇਕਤੈ ਥਾਇ ਰਾਖੇ ਮਨ ਹਰਿ ਜਪਿ ਭ੍ਰਮੁ ਭਉ ਦੂਰਿ ਕੀਜੈ ॥੩॥
bakaree singh eikathai thhaae raakhae man har jap bhram bho dhoor keejai ||3||
The sheep and the lions are kept in one place; O mortal, meditate on the Lord, and your doubts and fears shall be removed. ||3||
Guru Ram Das
