Siththars can be categorized but cannot be defined. They are unique among themselves. Though they differ with one another, the ultimate goal is same. All of them want to indulge or unite themselves into Lord Shiva, who is the beginning and end but each one of them followed their own way. But the ultimate goal is same.
Out of my reading experience, I have understood that the Siththars could be categorized in two ways. The first kind of them are those who consider all the earthly pleasure and sorrows are false and discard all of them and indulge or unite themselves into Lord Shiva and lead the rest of the life in that supreme pleasure. They do not consider anybody else.
Under this category, we can say Pattinaththar, Pathirakiriyar, Arunagirinadhar, Thaayumanavar as examples.
The second category is totally different. For attaining the immortality by following techniques like Alchemy they attain kaya siddhi and lead rest of the life.
Both categories of Siththars have done so many theurgies. These kinds of theurgies are the reason for attaining the attention of the people towards Siththars. None of the Sihthars has gone to the people by themselves and told about their inventions. Mostly for the benefit of their disciples only they reveal about their inventions.
They thought that human should realize about the uncertainty of life and attain the higher state of life. I think as a consequence of this thought only sidhaas thought that their inventions should never reach the common people who have got all the desires.
Thereby only, they have wrote all the realizations and understandings they got as songs with meanings hidden in them. So as to ensure that it do not reach the common man. Though the words of the songs comprises of simple words there is another meaning hidden in it. There is one such text in Bagavath Gita also, that could be quoted as example.
“In whatever form you think about me, I will appear in that form only.”
The Siththars language is also like this only. Those who are expert in this only can understand it and get beneficent out of it.
When they write the theurgy with hidden meaning in it at least out of the interest to know them they might attempt to understand the inner meaning. This might be the reason that the Siththars wrote their songs with a hidden meaning in it.
Hence by reading it deeply you can realize them.
