Dear Abrahma Kumar,
Omshanti. I am quoting from Q&A thread to answer your question.
"Any new person coming to any Ashram or Gita pathshala of AIVV is first of all given seven days’ basic knowledge and taught the method of RajYoga. After this he is explained the above mentioned Gyan Muralis and Avyakt Vanis. Later he is given the advance or deep knowledge of the above mentioned Murlis, Avyakt Vanis and the seven days course, which is being imparted by the Supreme Father Supreme Soul Shiva through the body of Spiritual Father Baba Veerendra Deo Dixit and is available in the form of audio, video cassettes, C.Ds, VCD*, DVDs or books. After the deep study of Godly knowledge, practice of RajYoga and inculcation of divine virtues, if he/she develops full faith on the corporeal role of the incorporeal Supreme Father Shiva, then he/she is given a voluntary option of giving an affidavit to this effect, in which inter-alia he/she has to give an undertaking that he will practice purity of thoughts, speech and actions throughout his life. After this, he is given a seven days intense spiritual training called RajYoga Bhatti at the ancestral house of the Spiritual Father situated at Village Kampila, District Farrukhabad, Uttar Pradesh,. On the successful completion of the training the person becomes a regular member of the AIVV family, who can participate in all the normal activities/ Godly services of AIVV. An extract of Godly version in this connection is as follows:
* “The course of seven days bhatti is very strict. One should not remember anyone. One cannot write letters to anyone. This bhatti of yours had been started. Everyone cannot be allowed to stay here. That is why it is said that you should stay at your home and practice.”- Murli dated 22.10.89
2. Any Brahmakumar or Brahmakumari coming to any Ashram or Gita pathshala of AIVV must also pass through the above said procedure. Since they have already obtained basic knowledge at the Brahmakumari Ashrams, they are directly given the Advanced Knowledge, and later imparted the seven days intense training (Rajyog Bhatti)."
