What is the difference between Yoga and meditation?

What is the difference between Yoga and Meditation. None. Yoga is meditation.

Yoga Meditation is the process of withdrawing the senses from the external world and going inwards. We begin our Yoga Meditation session with body poses, move on to breathing exercises and relaxation. Having touched upon the body and the level of energy, we are ready to gently approach the subtler levels of the mind and that which lies beyond.

 The word Yoga is often mistakenly used for body poses. This misrepresentation of the part for the whole is unfortunate. Yoga, as is understood and practiced in modern times, is often incomplete.
