Meditation, In Group Or Individual?

When the Buddha started his search for the truth, he went on a lonely path to seek the inner self and the immortal reality. His search went from moderate to extreme and finally back to ordinary life. He spent the last part of his life sitting under his Banyan tree and teaching others the lessons he had learned. Analyzing the path of truth shows that united effort is shared effort, and together we reach more than alone. When do you participate?
