What is "Trikal Sandhya" or "Trisandhya"? Why we should do Trisandhya?


According to Sanatan culture, during the three Sandhya(twilight) periods, In that Lord Mahavishnu is praised and thanked for controlling the creation and existence of the universe.
Morning-Brahma Muhurta(early morning), noon- and sunset (twilight) times are called Sandhya Kaal.
Morning Sandhya when night is over and sunrise takes place is one Sandhya Kaal.
Midday Sandhya when the day rises is one Sandhya Kaal.
Evening Sandhya when the sun sets, the day ends, and night arrives, is one Sandhya Kaal.
During these three times, Lord Mahavishnu is praised by all the Gods, Rishis, Munis, Yakshas, Gandharvas, Brahmaloka, Kailash Lok, Pitru Lok, Surya Lok, Chandra Lok, etc.(different entities and at different places in the universe)
Due to the severe effect of Kaliyug, Sanatan culture started vanishing and the daily routine of man and the Trisandhya routine vanished.
Once again, in the future, the great man Achyutananda Das Ji has said that Trisandhya Dhara is very important and necessary for the welfare of all human beings to get salvation from Kaliyug and to go to Satyayug.
