“All meditations are helpful...hundreds of techniques are available, but the essence of all those techniques is the same, just their forms differ.
And the essence is contained in the meditation Vipassana.
That is the meditation that has made more people in the world enlightened than any other because it is the very essence. All other meditations have the same essence, but in different forms; something nonessential is also joined with them. But vipassana is pure essence. You cannot drop anything out of it and you cannot add anything to improve it.” – OSHO
