A mind free from all disturbances is Yoga.
Yoga is the cessation of mind.
There is always a light within us that is free from all sorrow and grief, no matter how much we may be experiencing suffering.
If you can control the rising of the mind into ripples, you will experience Yoga.
Success is nearest to those whose efforts are intense and sincere.
Just as the pure crystal takes color from the object which is nearest to it, so the mind, when it is cleared of thought-waves, achieves sameness or identity with the object of its concentration.
