There are many descriptions in the scriptures that happiness is within, that is, it is in the soul, not outside. But I could not find any scientific explanation for this. Probably the form of the soul is like the existential void or the sky. In avidya or darkness there is one quality of the soul remaining, the void or the sky or the being. The quality of light disappears in it. That’s why the joy in it is greatly reduced, because all the qualities of the soul are related to each other more or less. In any form, the light that is experienced through the experience of the world, tries to fulfill the lack of light in the soul. What happens is that when that worldly light feeling is very fast, changing, i.e. dynamic or flamboyant or real like, then it cannot be mixed with the soul, because the soul is non undulating or changeless, like the nature of the sky, but on the contrary, the fast worldly feelings fluctuate quickly like waves of ups and downs means they are of the nature of change. One gets momentary happiness from them, as long as they remain, but as soon as they are removed, the darkness of the soul becomes more dense even from earlier. It is similar to how a person becomes blind for a while after coming out of bright light at night. When those worldly luminous experiences become dull due to non-attachment or Kundalini meditation etc., then they start matching with the empty soul. By this they give their light to the soul. Due to this, the lack of the soul is fulfilled and so bliss is felt, because according to the above scriptures, there is happiness in the soul itself, not outside. This is called satoguni avidya. Satogun is Prakash Pradhan. This is not only a matter of spiritual importance but also a matter of practical importance. Everyone likes a man who is calm and not the flamboyant one. The mental darkness of a person with a calm nature is also calm, while the mental darkness of a person with a fierce nature, ignorance of passion, is also fierce, deep and painful. This is the main difference between a gentleman and a scoundrel. The ignorance of a sage is due to being born of sattva guna, whereas that of a wicked person is due to being born of rajo guna and tamo guna.
When thoughts or mental images are changing rapidly due to passion, then their identity with the Pranamaya and Annamaya Kosha cannot be felt. Because later both are much more slow moving. Means it is difficult to consider them as one with the same combined body composition. Also the mental images related to common worldliness or livelihood are physical, because they are associated with the so-called material world, but the soul is immaterial, so they do not match. It is easy to associate mental images that are like static or slow and immaterial with this body group. In the Punjabi language and in the Sanskrit language, there is long path style or slowness, which increases the quality of goodness or sattvaguna. That’s why the use of these languages creates joy. The darkness of avidya that keeps on arising during worldliness through them, is the form of satoguni avidya. It is blissful. Similarly, keeping a beard like Sadhu Baba also makes a man’s behavior slow, contemplative, that is, satvik. This is why Baba remains intoxicated with bliss.
When a man attains a high position or object, the elders of the house keep him calm by preventing him from jumping too much. In our childhood, our mother used to bring us down from the sky to the ground immediately after some big achievement. In most of the cases, she did not let us fly in the sky of ego. She belonged to a family lineage of good and Vedic rites. If there is no contact of elders and sages in someone’s circle, then he flies far away with the achievements for a short time. Then, when the intoxication of flying breaks, he falls and starts drowning in the pit of depression, and the world starts considering him as crazy or mad, then he comes to his senses. But by then he would have lost a lot of joy and progress of the soul. That’s why it is not that this psychological principle of sattva guna avidya is applicable only in spirituality. This is equally applicable in worldly dealings too. Perhaps that’s why it comes in abundance in the scriptures that one has to suffer or do penance to attain knowledge. The scriptures believe that a person troubled by the sufferings of penance or lack of worldly goods will definitely find happiness in the soul.
When the gross body is also felt along with the thoughts, then the body gets their power and the burden of the brain is reduced. Means the force which was causing pressure in the brain gets transformed into the contraction of the muscles. Thoughts remain but fading with joy, they come to different chakras and dissolve. This happens because the chakras are not flooded with changing thoughts like the brain or mind. Infact chakra is not a dedicated organ for feelings like brain. Only one picture, mainly the Kundalini picture, remains on the chakras for a long time. This long stay of a sharp, quiet but unique mental image is a symbol of virtue. The avidya that arises from this is satoguni avidya. This is the bliss treasure. It is like a quiet and bright and non physical though unique candle flame mixed in the dark and quiet self more than other vibrant thoughts comparatively. Only the Kundalini picture that remains stable for a long time makes the best vigyanmaya kosha. It is a knowledge of immanent existence like the soul, but still a special knowledge. Meaning it is neither enlightenment or awakening, nor ordinary cosmic knowledge, but special knowledge or vigyan which is undoubtedly close to enlightenment.
