Yoga is the cessation of mind.
When you are inspired by some great purpose, some extraordinary project, all your thoughts break their bonds.
Progress is mediation comes swiftly for those who try their hardest.
In deep meditation the flow of concentration is continuous like the flow of oil.
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.
Success is nearest to those whose efforts are intense and sincere.
