Sun in Vedic astrology is the most important planet and it is visible to the naked eye thus HIS impact on our lives is more prominent.
Currently sun by transit is in the sign of Libra. Sun is debilitated in Libra(the lowest point). Sun ruled vitality and health – and when sun is debilitated it is common to experience tiredness, lethargy and the need for more sleep! It can also affect our health.
The best remedy for sun is to offer arghya to HIM – by chanting or listening to the Aditya Hrudayam Stotram(Sage Asgastya taught this to Lord Rama and that eventually helped HIM to win the war against Ravana) and the Surya mandala stotra(Lord Krishna taught this to Arjuna)
