With her thoughts fixed on the Lord, the Princess of Mithila entered the flames as though they were cool like sandal-paste, crying “Glory to the Lord of Kosala, whose feet are adored by the great Lord Siva with the purest devotion!” Both Her shadow-form as well as the social stigma (occasioned by her forced residence at Ravana’s) consumed in the blazing fire; but no one could know the secret of the Lord’s doings. Even the Gods, Siddhas and Sages stood gazing in the air. Fire assumed a bodily form and, taking by the hand the real Sri (Sita), celebrated alike in the Vedas and the World, escorted and presented Her to Sri Ram even as the ocean of milk presented Goddess Indira (Laksmi) to Lord Vishnu. Standing on the left side of Sri Rama, she shone resplendent in Her exquisite beauty like the bud of a gold lily beside a fresh blue lotus.
(Ramcharitmanas Lanka Kand, Shloka 108(1)

(Nobody, was aware of the fact that Sita, whom they were seeing, was merely a shadow. The real Sita had been preserved in the fire. Sri Ram wanted to have the real Sita. He played his illusionary acts and asked Sita to prove her chastity sitting in a blazing fire.)
About Planet's Period
 

There are nine plants in a horoscope who play major role in each event of one’s life for example; child-birth, education, profession, marriage in family and illness. These events can be seen by using Vimshottari Dasha (period) of a planet by it’s position, sign and degree in the horoscope. For example, Dasha (period) of the tenth lord gives professional-rise, Dasha of the third lord makes a person talented in fine arts, dance, music, sports and physical activities like exercise and yoga. Venus dasha makes a person good actor, gives marriage, functions and parties. There are some planets belong to unfavorable houses, these planets gives bad and unfavorable results during their period. These events and periods are the result of our past karmas. This can be judged by analyzing dasha (period) of a particular planet.
