Thank you, Sir for your blessings. I feel you would be happy to note that our son learnt the entire Vishnu Sahasranamam byheart at the age of five.
Thanks again,
Anamika.
Though learning Vedam from a learned gura is the best option,we may try using CDs and book ( Thaithriya manthra kosam with swaram by Anna,published by Sri Ramakrishna Mutt) in case we are not able to access a guru.
