People take the word Satsanga in the sense of few devotees sitting together & enquire about God & other related aspects to God. If all born blind people sit together & discuss about Sun, their conclusion is that Sun is black because they always experience darkness only & not even a trace of light. They can never turn even to right direction in spite of intensive & very long discussions. If a person having eyes in seeing condition gets associated with them, then only they can understand something about Sun.
Atleast, they can understand that Sun is not black by his preaching. Ofcourse, they cannot experience light even after his preaching. Hence, he will not speak about light at all. He can remove their ignorance but cannot impart knowledge about Sun. Hence, Shiridi Baba told that preachers speak about ignorance though not about knowledge. For these blind people, light is unimaginable because they never experienced light since they are born blind.
Similarly, people, who could never imagine unimaginable God in the past & who can never imagine God in future also, will certainly conclude God as some imaginable item in the world because they have experienced & imagined worldly items only. Atleast, they cannot even assume that God can never be imagined & hence, all worldly imaginable items are not God. Such ignorant people will conclude God as some experienced item in the world only.
Some imagine God as all pervading power or energy because they could imagine power or energy. Some imagine God as light & some imagine God as specific energetic form existing in some upper world. Some imagine God as self awareness, which is nothing but nervous energy. All these imaginable items like power or energy or energetic form or light or awareness are thought to be God because they were experienced items of the world by different people. When these ignorant people come in contact with Satguru, who is God in human form, will at least understand by His preaching that God is not any one of these imaginable items.
As the born blind people could understand at least that Sun is not dark by the preaching of a visualizing person even though they cannot experience the light, similarly, these ignorant people can understand that God is not any imaginable item by the preaching of Satguru even though they cannot experience the real nature of God (Andhenaiva… Veda).
The Satguru [Lord Krishna] preached the ignorant people that no one knows God in the Gita (Mamtu Vedanakaschana…). He did not give any positive answer about God by explaining the real nature of God. He gave only a negative answer about whatever is understood about God. Similarly, the visualizing person preaches the born blind people that Sun is not black. He will not preach that Sun is light because these born blind people can never imagine light.
Since, the real nature of God is beyond space and as our intelligence and imagination can never go beyond the three-dimensional space, we can never imagine the real nature of God. Hence, regarding the real nature of absolute God, only a negative statement of denying whatever is known is the possible preaching. Therefore, the Vedas also gave a negative answer only by negating everything that is imaginable to us (Neti Neti…). The Vedas gave several statements about the reason for such answer, which reveal that God is unattainable to words, mind, intelligence and logic.
Therefore, Satsanga does not mean discussion about God by devotees because it will be just like the discussion of born blind people about God. ‘Sat’ means Satguru or the absolute God in human form, who can alone explain about the unimaginable God.
