SIDHHANTHA PSYCHIATRY: The thathveehas that manifest in the various psychological space of human beings are further explained in saiva schools. AHANGARAM: self love(narcissism) they are threer types. Dhaisadham, vaiharam, boodhadhi, MANAS: manas is the mind in general. It has the following features. kamam, krodham, ulobam, moham, and madham. SIDDHAM: gunam(temperament) they have three types. Sathvam, rajas am and thamasam Thamasam: indiscipline,desire,anger,murderous behavior,lazyness,lack of remorse, excessive sleep, increased apetite, lying, forgetfulness, cheating etc It is to be noted these feature are seen in antisocial personalities, mania and depression. These syndromes are perfect examples of ancient psychiatric syndromal approach. Rajasam: brisk, knowledge, brave, benevolence, meditation, ethics, education, listening to elders etc. These are examples of well adjusted personality and may be an ideal modern mental health state. Sadhveeham: kindness, abstinence, wisdom, tolerance, gentleness, silence, truthfulness and minfulness. These states are not an ideal mental health states and may not compatible with worldly life. These may be an objective idealness rather than a practical way of life. Nevertheless these are the desired qualities of the men with closer union with god. PSYCHOMOTOR :talking, walking, hand works, excretion and procreation. PERCEPTIONS: touch,hearing,smell, taste and vision. SPEECH: sukkumai,paisanthi, maddhimai and vaihari. Thus the various psychological faculties are classified and the disturbances in them are tallied with the avathais. The avathai+physical symptom+psychological disorder together will constitute the holistic siddha medical system. It is the ancient model of psychosomatic medicine which is becoming popular in western countries. The psychosomatic disorders and their management is a relatively newer concept (10 years) in western countries. But this approach has been well estabilished in the tamil medical system. METHODS OF LOGIAL INVESIGATION: The investigation of a theory and proving it empirically needs investigatory tools. These tools are the tools of logic or tools of science. An idea is theorized to become a hypothesis. A hypothesis is tested according to the logical tools. When it is proved it bocmes a thesis. This is what a modern scholar in science tries to do when he presents his research. The objectivity of a theory is important in science. Psychological theories have to be proved similiarly. Psychologicaltheories are becoming tested only for the past hundred years. The testability of the psychological theories like behavioral theories by IVAN PETROVICH PAVLOV heralded the delineation of psychology from philosophy by WILHELM WUNDT hundred years ago.
Logical methods were used atleast thousand years ago in philosophy and psychology by saiva scholars. These are called the "BRAHMANAM" (ALAVAI-IYAL) in saivasiddhantha. The logical methods and steps are ten. They are, 1.visual conformation=katchi=pradhyatcha 2.thinking=karudhal=anumana 3.theories=urai=agamam,sabthapramana 4.falsification=inmai=abhava 5.truth=unmai=sambava 6.example=uvamai=ubamana 7.cancellation=ozhibu=pariseda 8.traditional=vazhaku=aidheeha 9.natural=iyalbu=sagaja 10.abstraction=porulperu=arthabathi
Theory testing follows the initial intuition and the tested concept are hypothesized. The hypothesis is given to logical investigation. The psychological states initially described are thus tested on the individuals and then they are theorized. Later they become scriptures. It is to be noted the psychological phenomena were described by KARL JASPER in late 19th century and they became PHENOMENOLOGY. Simultaneously the mental states were experimented to reason out the cause by SIGMUND FREUD in early 20 th century. That became PSYCHOANALYSIS. When phenomenology was a descriptive method the psychoanalysis was a investigatory science. Saiva siddhantha had both these components. The field of HERMENEUTICS spearheaded by PAUL RICOUER from France was aimed at studying these scriptures to prove the human psychoanalysis and folk psychology. Modern study of saiva siddhantha is also a hermeneutic method and is capable of proving the same as Freud and Jasper aimed at.
