Dear Sister Sarah,
Omshanti. Amrit Vela is not a new concept developed by BKWSU but a tradition being followed by Indians since many centruries (or since the beginning of the Copper Age in BK terms). Amrit Vela is generally considered to be the pre-dawn period. Well, this period may differ from area to area or from individual to individual. Some may consider it to begin at 2 AM, some at 3 AM or some at 4 AM. For BKs, it is considered to ideally begin from 3 AM, but for PBKs it is considered to ideally begin from 2 AM. But again, it is not compulsory and depends on the interest/inclination of an individual. I guess most BKs/PBKs wake up at 4 AM.
The period of Amrit Vela is considered to be pure because of both physical/environmental and spiritual reasons. I need not explain the physical/environmental reasons, but from spiritual point of view it is believed that the atmosphere remains generally pure because people do not not commit any sin (including lustful acts) during this period. Even the vibrations of human beings are pure because most people are fast asleep at that time. So, those who wake up during this period and pursue studies or spend their time in devotion/worship/Baba's remembrance reap the maximum benefit when compared to other times of the day/night. Moreover, it is believed that the efforts made during the Amrit Vela have a good effect througout the day.
From PBKs point of view, Amrit Vela is interpreted both in physical and metaphorical sense. In metaphorical sense, Amrit Vela is believed to be the period from when a soul recognized the part of Sun of Knowledge being played by ShivBaba (through Baba Virendra Dev Dixit). Since the revelation of ShivBaba through Baba Virendra Dev Dixit began from 1976, the Amrit Vela for PBKs in an unlimited sense is believed to be from the time they recognize the new corporeal role of ShivBaba. Nevertheless, Amrit Vela, i.e. practice of meditation during the pre-dawn period is equally important. Even in a recent discussion CD No.435 ShivBaba (through Baba Virendra Dev Dixit) clarified the importance of Amrit Vela in both limited and unlimited sense. I will try to quote the extracts.
