For meditation to be effective one should not lie down for it. The reclining position is not suitable because it causes sleepiness and fatigue of the mind. The mind should be neutral for meditation, neither too dull, nor too active.
The most popular posture for meditation is the Lotus Posture (Padmasana). However, since it may be hard to master, any comfortable sitting position with the spine straight and in line with the neck and head can be used. The easiest suitable position is Easy Posture (Sukhasana). If it is not possible to sit cross-legged, Egyptian or Chair Posture can be used. Perfect Posture (Siddhasana) or
Hidden Posture (Guptasana) are also suitable.
