I'm sorry if I my posting was inappropriate or if I offended you in any way, Sanghamitta. Nowadays, I feel mostly drawn to Theravada but I have been influenced and inspired by many teachers of different schools. I also think that there is a huge amount of skilful means availabale to us and that we should use what is beneficial. Zen, Vajrayana and Theravada are merely labels. Ultimately, all those different schools date back to the Buddha. Many different schools, one Dharma/Dhamma. For what it's worth, you could probably also find Theravada teachers instructing their students with one of the methods I mentioned above.
PS: Collective, what Sanghamitta suggested is probably the most useful. Find a teacher who can instruct you in person
