Meditating on what is unimaginable is considered to be the ultimate sadhana. It is supposed to be beyond any conceptualisation. If we imagine light, that is also a kind of form. If the mind keeps thinking about the term unthinkable to focus on, that is also limited in sphere. So it is a challenge which one has to overcome, and the secret is that it can be attained by not pursuing anything with an intention to pursue, by becoming absolutely blank.
That’s the state of godhood the state of no-action in every sense that supplies the energy for all action. For example, the universe is said to have emerged from a point. That’s easy for us to understand. We draw the example of seed and the huge tree coming out of it gradually . Otherwise, in true sense it is not even a point, it is mahashunya, nothingness. Why do we need sadhana of the unthinkable? We need the strength to pursue the most fruitful action. Ramakrishna talks about three thieves representing three gunas: rajas, tamas and sattva. They are called thieves because all three distract us from the state of no-action. But the difference is that when rajas can make you exhausted and tamas can completely destroy you, sattva is a thief which has lot of compassion. He guides you to the road that takes you safely home, the state of no-action.
Kabir Das called this Sahaja Yoga. If we can become completely blank even for a moment, that is the real state of God-realisation. In deep sleep, we may attain this stage. But from a spiritual point of view, this state has to be experienced when we are awake.
It is very difficult to become comple tely thoughtless. After remaining blank for a while one may feel sleepy but even then it is worth practising. The effort to make ourselves thoughtless is also an action. So that action also has to be discarded. To imagine a point and then to focus on it is also an action. But as a beginner, we may take some form or light and remain blank which may ultimately lead to the state of nothingness and thoughtlessness.
A sage suggested, you may think of God’s feet to begin with but do not try to perform anything on the feet. Just remain stable. A state will come when the feet will disappear; what would remain is nothingness. That is why Ramakrishna explains with lucidity that guru merges with `Esta’ or Being, and ultimately there remains nothing. So the guru may jokingly ask you to offer the guru dakshina first and then he would impart his teachings. Otherwise at a later stage there would remain no guru.
As one attains this state of nothingness spontaneously, permanent peace prevails. And one draws energy from that state of no-action to pursue enormous action for human welfare.This state cannot be described in words.
That is why it is said that Brahmn is unspeakable. Even one who realises cannot utter a word about it. Buddha simply smiled and said nothing as he was asked to comment on nirvana. It is for individuals to experience it. Those who follow the path of sadhana and human welfare are able to perform this selflessly. Nishkama karma becomes possible only for a yogi at heart.
