There is a bridge between time and eternity; and this bridge is the spirit of man. Neither day nor night cross that bridge, nor old age, nor death, nor sorrow. Evil or sin cannot cross that bridge, because the world of spirit is pure. This is why when this bridge has been crossed, the eyes of the blind can see, the wounds of the wounded are healed, and the sick man becomes whole from his sickness. To one who goes over that bridge, the night becomes like unto day; because in the world of the spirit there is a Light which is Everlasting. -- Upanishad's 600 B.C.

I hear the melody of His flute, and
I cannot contain myself:
The flower blooms, though it is not
spring; and already the bee has
received its invitation.
The sky roars and the lightning flashes
the waves arise in my heart,
The rain falls; and my heart longs for my Lord.
Where the rhythm of the world rises and falls,
thither my heart has reached:
There the hidden banners are fluttering in the air.
Kabir says: 'My heart is dying, though it lives.'

Prem Rawat's "Knowledge" has three parts: regularly listening to his speeches, doing voluntary work for organisations serving him or donating money and daily meditation correctly practicing the four techniques he recommends. The techniques are so simple it's hard to see how they could be practiced incorrectly. First technique ("Divine Light") involves sticking your thumb and middle finger on your eyeballs (NB: with eyes closed) and your index finger between your eyebrows. Second technique: ("Heavenly Music") poking your thumbs into your ears and listening. Third technique: ("Holy Name") thinking about your breathing (NB: continue to breathe). Fourth technique: ("Nectar") curling your tongue backwards and tasting. Rawat's father taught slightly different techniques but either way it's difficult to see how these could produce the benefits claimed for them especially as Rawat claims His Knowledge is the only method of attaining real happiness and love in this life.
