Esoteric Buddhist practices

I started studying and practicing the Buddha-Dharma fairly recently and I was wondering if any fellow GLPers have any input on any teachings. Or perhaps some information on or about the lineage they practice.

Some of the practices/teachings/concepts that interest me include:
Tummo (dummo) or heat yoga
Phowa, Pho-ba
Dream Yoga
Tantra
Vippasana
Tulpas
Siddhis
Bardo
stream-enterer
Ngondro
Vajrayana
Tathagata
Yidams
Puja
Yogacara
Bhavacakra
Dependent origination

It would be very interesting to see if anyone else is interested in this or other subjects and maybe wants to trade some information and or resources :D
