The witness (drasta), looks on passively but consciously, with acute alertness. It never participates in that which is looked at. It stands aloof and separate, a step away, as it were. The seen is 'there' and not 'here'. See the mind in operation. It is drsya, you are drasta. Look at it, don't deny or assert.
I see a dream that I am getting ready to go to Kerala. I pack my things, get into a taxi, reach the railway station, purchase a ticket and get into the train. The train meets with an accident on the way and I am killed and so on. But, who saw the dream? Who looked on even when I was killed and cremated? Who is the one that looked on, but remained aloof, uninvolved? As a radium-dial watch needs to no other light to illuminate it, if the dust that covers it is removed, even so, when body, mind and intellect are swept aside, 'I', the self-luminous, stands self-revealed.
If this is understood and comprehended, one ever remains in meditation. There is, then, no need to allot a particular hour to meditation. Meditation becomes an unbroken experience of life.
