Directions for the following 3 (three) items:

Read the following two passages and answer the items that follow. Your answers to these items should be based in the passage only.

Passage 1

Vivekananda realizes that mankind is passing through a crisis. The tremendous emphasis on the scientific and mechanical ways of life is fast reducing man to the status of a machine. Moral and religious values are being undermined. The fundamental principles of civilization are being ignored. Conflicts of ideals, manners and habits are pervading the atmosphere. Disregard for everything old is the fashion of the day. Vivekananda seeks the solutions of all these social and global evils through education. With this end in view, he feels the dire need of awakening man to his spiritual self-wherein, he thinks, lies the very purpose of education.

Vivekananda points out that the defect of the present-day education is that it has no definite goal to pursue. A sculptor has a clear idea about what he wants to shape out of the marble block; similarly, a painter knows what he is going to paint. But a teacher, he says, has no clear idea about the goal of his teaching. Swamiji attempts to establish, through his words and deeds, that the end of all education is man-making. He prepares the scheme of this man-making education in the light of his overall philosophy of Vedanta. According to Vedanta, the essence of man lies in his soul, which he possesses in addition to his body and mind. In true with this philosophy, Swamiji defines education as ‘the manifestation of the perfection already in man.’ The aim of education is to manifest in our lives the perfection, which is the very nature of our inner self. This perfection is the realization of the infinite power which resides in everything and every-where-existence, consciousness and bliss (Satchidananda). After understanding the essential nature of this perfection, we should identify it with our inner self. For achieving this, one will have to eliminate one’s ego, ignorance and all other false identification, which stand in the way. Meditation, fortified by moral purity and passion for truth, helps man to leave behind the body, the senses, the ego and all other non-self-elements, which are perishable. He thus realizes his immortal divine self, which is of the nature of infinite existence, infinite knowledge and infinite bliss.

Q.33) According to the passage what is PERFECTION?

  1. Things are proper at top to bottom.
  2. There is no scope for undone things.
  3. It is an expression of mankind.
  4. Nature of inner-self and realization of infinite power.

Q.34) According to the paragraph what is the purpose of Education?

  1. Obtain the clear goal of teaching.
  2. To understand that the end of all education is man making
  3. Education should be free learning
  4. Education is everything.

Select the correct answer using the codes below:

  1. 2 only
  2. 3 and 4 only
  3. Neither 1 and 2 nor 3 and 4
  4. All of above

Passage 2

A German proverb proclaims that a man is what he eats. It could equally have insisted that he is also what he does not eat. Indeed, a man is also what he wears, speaks, believes, worships, smells, the music he listens to, how he dances and the colours that entice him. This list can multiply, and multiply differently for different people. Human diversity is rich and immense.

India’s own diversity is among the richest: countless culinary habits, dress, customs and musical traditions; more than 200 different dialects and languages; religious and doctrinal diversity, the ritual-oriented Vedic practices, the teachings of Buddha, Mahavira, Zarathustra, the Torah, and Guru Nanak, the religiosity in the Puranas, Islam, Syriac-Christianity, the great varieties of animism and atheism.

Q.35) What is the author talking about in the passage?

  1. Diversity of humans as a whole as well as India’s own diversity.
  2. India’s rich diversity only.
  3. Religious and doctrinal diversity of India.
  4. The greatness of Indian traditions.
