You can't force through these stages with force, impatience and mere techniques as is the habit of us westerners. Even more important if the desire is strong then it backfires. One should also look at how subtle levels of inner clinging and desire interact with the external world which is a whole different area. The ground in Dzogchen is different than in Yogachara too. Also there are different categories of rtsal manifestations. If none of these five separate areas convinces one, then it is good to keep in mind what we are told, namely that handling these things wrongly or too impatiently or wanting them too much or even liking them before or after initial basic arising can block them for the current lifetime. This page is all wrong.
Dzogchen masters I know say: 1)Buddhist religion essence is Dzogchen 2)Religions are positive by intent/fruit 3)Any method's OK unless: breaking Dzogchen vows, mixed as syncretic (Milanese Soup) 4)Don't join mandalas of opponents of Dalai Lama/Padmasambhava: False Deity inventors by encouraging victims 5)Don't debate Ati with others 6)Don't discuss Ati practices online 7) A master told his old disciple: no one's to discuss his teaching with some others on a former forum nor mention him. Publicity's OK, questions are asked from masters/set teachers in person/email/non-public forums~Best wishes
