Answer: In the autobiographical essay Strong Roots, Kalam’s father reveals the fundamental truths to Kalam.
Here the phrase “fundamental truths” refers to those truths that are uniformly admitted as the pillars of establishment in life. Kalam’s father reveals to little Kalam such certain truths. He gives him knowledge about the benefits of prayers and tells him that through prayers, one transcends his earthly presence and becomes a part of cosmos. Another fundamental truth revealed to little Kalam is that every human being is a part of divine being; so, we should not be afraid of adversity of life. Besides, Kalam comes to know from his father that inessential luxuries, comforts must be ignored in life.
