Glory of Rama Nama - Why Vashisht Maharishi chose the name Rama?

In these days, parents themselves select the names for their new born babies. In ancient times, and even just before 100, 200 years before, a Guru, or Grandfather or some other learned person will give name to the new born baby. The responsibility of choosing an appropriate name to the newborn has been entrusted to these people with an idea that these elders or learned persons would be able to determine the most appropriate name.
