In ancient India when the Buddha taught his disciples, monks lived in the forest.
Meditators lived on the road throughout their lifetime. They practiced sitting under trees and slept on a sheet or blanket (their robe) in the forest. They kept silence all the time. Minds awakened and kept peaceful.
One can practice Sati Meditation at all times, focusing on the present moment.
For example, just sit under a big tree and close your eyes. Foliage moves gently in the breeze. You just focus on your belly’s movement. This is where a meditation begins.
