Not sure what the OP or the person in the videos means but a direct, fast way I have found to “drop in” is to stop thinking and intensify my awareness of everything. Takes about 5-10 seconds to transition into a nonthinking timeless presence.
Attention is on the full body, and the field of perception, then field of awareness, all at the same time.
A bit like shavasana practice, but instead of scanning part by part, expand presence to everything.
The thinking analytical mind stops, the nonthinking mind activates and softly intensifies.
Yes this would be one “provisional” method among many, maybe hundreds of techniques but they all seem to lead to the same place as one gets familiar. In Buddhist Vajrayana schools this is called “non-meditation”. The ultimate instruction is to simply do nothing, but this requires a bit of initiation (and paradoxically, concentration) to get right.
Michael Taft has many different guided approaches to this on his channel but there are many other teachers as well, e.g. Adyashanti, Angelo Dillulo, Loch Kelly, Shinzen Young (specifically his Do Nothing and Auto Focus techniques) and expanding the gamut to traditional Vajrayana teachers, Lama Lena, Mingyur Rinpoche, Lama Dawai Gocha, all with accessible online teachings. Also Sayadaw U Tejaniya and Christopher Wallis who are less conventional, so to speak.
