Without an intense urge to know the truth and sharpness to grasp the truth, it is difficult to tread the path of wisdom.+*****

The path of wisdom is not for those who are not in search of the truth of their true existence.  

According to Advaita Vedanta, the Veda addresses itself to two kinds of audiences - the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of ritual sacrifices, and the more advanced seeker who seeks to know Brahman. Thus, the Purva mimam.sa, with its emphasis on the Karma kanda of the Vedas, is meant for the first audience, to help lead its followers along the way. However, the Vedanta, with its emphasis on the jnana kanda, is meant for those who wish to go beyond such transient pleasures.

Orthodox people are ordinary people. Thus,  the ordinary ones who desire the transitory heaven and other pleasures obtained as a result of rituals, sacrifices prayers. The Karma kanda of the Vedas is meant for the ordinary audience, to help lead its followers along the way.

Modern mindset is more advanced and capable of reasoning and discriminating. Thus, modern mindset is more advanced which seeks to know the ultimate truth or Brahman.

As per the scriptures, the three "Ashrams" or stages in life were originally intended for three grades of intelligence thus:~

v          Low intellects:~ Follow Religion and have to do 'karmas' works, ritual actions, chanting of mantras and indulging in bhajans and prayers, etc.

v             Middle intellects:  Yoga: taking yellow robes, going to caves, ashrams, etc.

v             High intellects: wisdom who wanted the truth is concerned with no external rites no prayers or sanyasa but depend solely on the Soulcentric reasoning for their path.

Thus, the seeker has to choose his path,  according to his choice.  Without intense urge to know the truth and sharpness to grasp the truth, it is difficult to tread the path of wisdom never mix different path with each other and make cocktail because it leads to all sorts of doubts and confusion. 

 The seeker of truth should be beware of everything that is untrue: stick to the truth and he shall succeed, maybe slowly, but surely.

The Soul, the Self, is the witness. The Soul is prior to anything that exists. The three states (witnessed) are merely an illusion from the standpoint of the Soul, the innermost Self. The Soul is the subject and the three states are an object to the formless subject. In Self-awareness,  the subject and object are one in essence. That essence is the Soul, which is present in the form of consciousness. Thus the consciousness alone is real and all else is merely a dualistic illusion or Maya.:~Santthosh Kumaar
