Asking for some general information about Yidam practice. Especially among Nyingma Lamas and Longchen Nyingthig practitioners.
I was under the impression that perhaps you'd have one or two Yidams. And if you took Senge Dongma as your Yidam for example, she would be both your Yidam and your Dakini and, ultimately, your Guru's manifestation. Maybe you would also practice Medicine Buddha or something...and that was it. Until enlightenment SHE was your generation phase.
Now I'm confused because maybe the three roots are more like three seperate sadhanas for each practitioner? Like you accomplish a Guru sadhana like Rigzin Dupa, then also a yidam (which categorically seems to mean wrathful deity--unless it's Vajrasattva) and also a Dakini like Dechen Gyalmo. I've read that the Sakya and Gelug schools also must practice all their deities every day whereas the Nyingma and Kagyu are more all-in-one.
I can't help but think of Atisha's quote "Indians practice 1 deity and accomplish 100 siddhis; Tibetans practise 100 deities and get destroyed by them."
