Pt. Shri Pranesh Achar (Ananda Rangan)

The answer to this is that there is a saying in Manusmriti.
It is said that in the morning, one should especially meditate on God. The suitable time for us to meditate on God is the dawn period. That is called Brahmi Muhurta.
It is said that at that time, one should wake up and especially remember and meditate on the Lord. "Brahme Muhurte Utthaya Dharmaarthaavanu Chintayeth Kaaya Kleshaanshcha Tanmoolan Veda Tatvaarthameva Cha".
