"Thought" generally refers to any intellectual or mental activity. It can refer either to the act of thinking or the resulting ideas or arrangements of ideas.
Fir vahi naye subah aye hai,
Suraj ke roshni se chaye hai,
Dil youn he roshan ho humara,
Bun ja a aaj fir acha din hamara,
Pa lain jo na paya kal,
Je lain fir ek or ban ker anmol setara.
