Two Forms of Meditation

There are two kinds of meditation, one on the formless God and the other on God with form. But meditation on the formless God is extremely difficult. In that meditation you must wipe out all that you see or hear. You contemplate only the nature of your Inner Self. Meditating on His Inner Self, Shiva dances about. He exclaims, 'What am I! What am I!' This is called the Shiva yoga'. While practising this form of meditation, one directs one's look to the forehead. It is meditation on the nature of one's Inner Self after negating the world, following the Vedantic method of 'Neti, neti'. 

There is another form of meditation, known as the 'Vishnu yoga', The eyes are fixed on the tip of the nose. Half the look is directed inward and the other half outward. This is how one meditates on God with form. Sometimes Shiva meditates on God with form, and dances. At that time he exclaims, 'Rāma! Rāma!' and dances about.
