Analysis of information sources in references of the Wikipedia article "Avatamsaka Sutra" in Portuguese language version.
The term "avatamsaka" means "a garland of flowers," indicating that all the virtues that the Buddha has accumulated by the time he attains enlightenment are like a beautiful garland of flowers that adorns him.
...adornment, or glorious manifestation, of the Buddha[...]It means that countless buddhas manifest themselves in this realm, thereby adorning it.
The title Gaṇḍavyūha is obscure, being generally interpreted as 'array of flowers', 'bouquet'. it is just possible that the rhetorical called gaṇḍa, a speech having a double meaning (understood differently by two hearers), should be thought of here.
