Yeah same for me. I started doing meditation about one year before my first encounter with DMT. I started with 5-Meo-DMT back then and this really helps a lot. For me, 5-Meo-DMT is a very straight forward tool when it comes to working with deep meditation states. I have also done some Vipassana-retreats, where sometimes I reach states similiar to higher doses of 5-Meo-DMT but without any help of a drug.
My ritual every 2-3 weeks is to do meditation for two hours, then snort a big line of 5-Meo-DMT (let's say 20-50mg), and as soon as my awareness of body, time and place returns do another 1-2 hours of meditation. Sometimes I add some vaped DMT for the nice colours.
Also 2-3 times a week I smoke a low dose of 5-Meo-DMT and/or DMT before I start my daily meditation. Makes things a lot clearer.
Of course doing a lot of meditation on a regular base makes it very easy for me to reach deep states on psychedellic drugs and also without psychedellic drugs. So meditation is my primary tool, the drugs are 'only' for the occasional excitement.

So far I don't have any experience with oral DMT/Ayahuasca but I imagine it will be a very very profound experience to combine this with a long session of deep meditation.
