Final answer:
Colin Craven's transformation in 'The Secret Garden' parallels the theme of healing and rejuvenation through nature, as his contact with the garden helps him overcome physical and psychological barriers.
Step-by-step explanation:
Throughout Frances Hodgson Burnett's The Secret Garden, the transformation of Colin Craven is more than a narrative of physical healing; it mirrors the novel's central theme of rejuvenation and the healing power of nature. Initially bedridden, Colin is described as a pessimistic, frail boy who everyone believes is destined for an early death due to his supposed myriad of ailments. However, as Colin begins to spend time in the hidden garden, which itself is transforming from a desolate space into a lush, vibrant haven under the care of Mary and Dickon, his health and outlook on life improve dramatically. This transformation aligns with the novel's theme that being in touch with and nurtured by nature can lead to inner and outer growth. Supporting this is Colin's newfound ability to walk and his decision to embrace life, thus overcoming his fears and the psychological barriers imposed by his father and the household staff.
