ज्योति कलश छलके

The raag is what attracted to me to the song first, and I subsequently discovered that it celebrates the onset of morning.

अल्लाह तेरो नाम, ईश्वर तेरो नाम

This song brings out the secular nature of God, although only two forms of God are mentioned here:

1. Allah of the Muslim faith, 
2. Eswar of the Hindu faith. 

It also wishes for goodness in the world, in expressing that:

1. Everyone be blessed with good mind
2. Wives not lose their husbands. (This is probably a reflection of the time; women tended to be more dependent on men those days than nowadays).
3. Mothers' and sisters' not fulfilling their hopes
4. Life not be stifled by a [weak] body
5. Everyone be blessed with knowledge of God

The foregoing is nothing but an elaboration of another well-known Sanskrit phrase, वसुदैव कुटुम्बकं, or "The whole world is one family".

Above all, it is a beautiful rendering by the incomparable Lata Mangeshkar.
