1. Real Amrit is obtained via Dasam Duaar so there's no need for Khande De Phaul right?
Having "Khade Di Pahul" means having initiation into any sort of spirituality, through the process approved by Guru Nanak Guru Gobind Singh. Those who do not feel proud of making relation into Guru Gobind Singh's close family, can try any sort of damn things.
2. Can Brahmgian can be obtained within 4 years or so in a University Brahmgiani Course?
Brahmgian is more of a blessing and less of the efforts. It may happen in four seconds or in four centuries. It happens once a while in decades. It had been more common sense of those people offering this course, to call it as University Course in Divinity.
3. Is Khande Phaul, is it necessary as the real way is Naam Simran only?
Who says NAAM SIMRAN is the real way, it is always said as NAAM SIMRAN through GURU.
4. Passing through the tats (elements) of the body causing shaking and also extreme fits is normal whilst doing Simran?
And they may also call a person under fits, as enjoying AMRIT from DASAM DUAAR.
5. Can Amrit Rass can it be experienced without be Amritdhari?
Those who want to try it other way, can try it anyway.They do not like to be called Amritdhari Khalsa of Guru Nanak Dev Sahib Ji.
6. Not much attention need to be paid to Rehat & Nitnem as the real way is Naam Simran?
Crops need management. Naam Simran is not purely mechanical repetition. It needs proper nutrition and management.
