this is a saying of Lord Ram chandra ji to laxman ji when he was sitting with laxman ji in panchavati waiting for the rainy season to pass so that they may start searching for Sita ji again in far regions of the South India

Lyrics-

Ghan ghamand nabh gartjat ghora ,piya heen darpat man mora
Damini damak rahat nabh mahi , khal ke preeti jatha thir nahi
Barasahi jalan bhoomi niyraaye , jatha nabhahin guni vidya paaye
Boond aghat sahayin giri aise , khal ke bachan sant saha jaise
Chhudra nadi bahi chali tyorayi , jas tyoreiun dal khal itrai
Sarita jal jal nidhi mahoon jaayi , hoohin achal jin jeev hari paayi .

One must should understand meaning of this song . It is really a milestone in defining nature of goodness in a person .

Meaning -

Sri Ram chandra ji says to Laxman ji :

The proudy clouds are roaring in the sky ,my mind is being afraid without my sweetheart(Sita ji).
The lightening is making the clouds bright in the same way as the love for one is not stable for a wicked .
The rainwater is falling down to flow on the land in the same way as the knowledge itself moves towards a skilled person .
The mountains are tolerating the impact of the rainwater drops in the same way as nobel person tolerate the abusing words from the wicked.
The little river after getting the rainwater flows inundating the areas being overwhelming in the same way as the group of the wicked gets overwhelming after getting little.
The streaming riverwaters are falling in the ocean and are getting calm like ocean in the same way as the disturbed soul(atma)or jeev becomes peaceful after mixing in the supersoul(paramatma)or Hari.

Rann jiti Ram rau aayen - This is the song illustrating the scene just after Ram chandra ji won the battle and then returned to Ayodhya
