Please enlighten me with 'Amrit Vela'. Is this related with timings. Recently, It came to my ears that

Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=55
12 midnight - 3 am: Saints, Mahapurush do Nitnem
3 am - 6 am: Grahsthi jeev do Nitnem

Even there was some talk about having multiple times benefit of doing Nitnem at these times compared to other times upto 12 noon.

Thanks.
