Can I use a Ponto Riscado as a sigil and just open it?

It seems that goetic spirits, demons and angels are more “ok” with the reinvention of the rituals in the modern magick and many of them don’t really care about incense, circles, triangles, clothes and candles if you don’t in my experience. But the african and the latine spirits seems very connected with this traditions, so what do you guys think?

Yes, but use a little bell for calling The spirit first
