    This gesture indicates Meditation, or more exactly the highest state of tranquility (Samādhi or sānmótí 三摩提).

Although long used in India as a position for the hands during Meditation, in Buddhist Art this gesture is usually associated with Buddhas, therefore usually Sakyamuni or Shìjiāmóuní fó 释迦牟尼佛 釋迦牟尼佛 and Amitābha or Ēmítuó fó 阿弥陀佛 阿彌陀佛.
 
    (A begging bowl may be held atop the hands. When a medicine bowl is shown there, the figure is often Bhaiṣajyaguru, known in Chinese as simply Yàoshī fó 药师佛 药师佛 藥師佛, which means “Medicine Master Buddha,” associated with Healing.

Or it is Ēmítuó fó 阿弥陀佛 阿彌陀佛 (Amithābha), especially if both hands remain the Meditation Gesture position.

In some cases only one hand is used in order to free up the other hand to perform a different mudrā.)
