The Thai forest tradition is almost solely focused on meditation.
As the tradition's name indicates, the monks often wander in the forest by themselves meditating for years on end.
Sutta and book learning are not emphasized, Ajahn Chah said "The only book worth reading is the your heart"
There are some Thai forest monasteries throughout the world but depending on where you live it might not be easy to find one nearby.
Thanissaro Bikhu is a senior Thai Forest Monk and publishes the daily talks he gives at his monastery in California on dhammtalks.org.
This a great resource, especially if you don't have a teacher nearby.
