‘converge’: When the citta gathers all of its outflowing currents into one point, this is known as the citta ‘converging’. The practice of samãdhi meditation is a method for concentrating all of these diverse currents into one focal point, thus centering the citta into a condition of complete stillness and calm.

集中(converge)：心把外流的意识往内汇聚成一点，即心的集中。三摩地的修行是用方法把散乱的意识专注到一个焦点，把心集中到一个完全静止和定的境界。
