Mundaka Upanishad: ~ The study of the Vedas, linguistics, Rituals, astronomy, and all the arts can be called lower knowledge. The higher is that which leads to Self-realization.+

Ish Upanishad:~Those people who have neglected the attainment of Self-knowledge and have thus committed suicide.

Those people who have neglected the attainment of Self-knowledge and have thus committed suicide, as it were, are doomed to enter those worlds after death.

This is a condemnation of people who do not try to attain Self-knowledge. They are, in a real sense, committing suicide, for what can be worse than being a slave to sense enjoyment, completely oblivious of the real purpose of life, which is to be one's, own master?

Mundaka Upanishad: ~ The study of the Vedas, linguistics, Rituals, astronomy, and all the arts can be called lower knowledge. The higher is that which leads to Self-realization.

The eye cannot see it; the mind cannot grasp it. The deathless 'Self' has neither caste nor race, neither eyes nor ears nor hands nor feet. Sages say this Self is infinite in the great And in the small, everlasting and changeless, The source of life.

Self-knowledge or Brahma Gnana or Atma Gnana needs no philosophy! In spite of reading and explanations, words are after all mere words. They do not take one any further than mere intellectual satisfaction.

An intense urge to realize the truth works the miracle because the ultimate truth is beyond form, time, and space. There is no necessity to study and understand the scriptures. There is no necessity to follow anyone. Those who want to realize the ultimate truth need not read any philosophy. Studying philosophy is not necessary to realize the truth beyond form, time, and space.

All these confusions will go on until the man thinks, he is an individual and apart from the world, and the world existed prior to him and he is born in it afterward. Therefore, it is necessary to know the fact the true Self is not the ego, but the true Self is the Soul, and stop viewing and judging the world-view from the standpoint of the physical self (ego), and one has to view and judge on the true Self (Soul) to realize the fact that, the world along with the man is an illusion.

The Soul which is present in the form of consciousness is the cause of the illusion. The Soul is the ultimate truth or Brahman. From the standpoint of the Soul, the innermost Self, there is no second thing that exists there is neither experience nor the experiencer in non-dual reality, but only Self-awareness. : ~ Santthosh Kumaar
