(Sri Vaayu Stuti sloka # 4)

We all know very well that Madhva is the name of Sri Aananda Theertharu who is also called as Madhvacharya; an incarnation of Lord Vaayu the Mukhyapraana;

Madhva is not just a name alone, rather,

it is a divine name, 
a vedic name, 
name of a philosophy (Dvaita/Tattvavada), 
a title conferred upon Sri Aananda Theertharu 
who is Poornaprajna;
known from Vedic scripts;

Madhu + Va = Madhva;

Madhu means honey/happiness; Va signifies the knowledge;

Madhva means the knowledge that gives happiness which is as sweet and delicious as Madhu (Honey);

Aachaarya means preceptor;

Madvhacharya means the one who gives knowledge of happiness or whose knowledge gives happiness; happiness of removing all wrong tenets;

the one who gives the knowledge of Madhusuudana (“Madhavo-Madhusuudana”) the supreme God - Hari Sarvottama; the lord and bestower of superior knowledge;

Aananda means the one who gives delight/happiness;

Lord Vishnu is known as Aananda ("Aanando nandano nandah"...) - Sri Vishnu Sahasranama Stothram (sloka # 56)....

the one who is always joyous; 
the one who gives delight (Aananda) to this universe;
He is the origin of happiness;
the ultimate abode of delight and is perennially blissful;
He is the remover of all unhappiness;

In fact both the terms Madhva and Aananda are identical in giving the meaning of happiness;

Sri Ananda Theertharu is the one who proclaims the superior divine knowledge which gives ultimate happiness to the followers of Sri Madhvacharya the one who has put to rest all doubts;

We come across reference to the divine name MADHVA in several vedic scripts (Madhvaakyam-Mantrasiddham) like...

The deity whose three divine forms are spoken in Vedas, 
as one whose nature is that of great wisdom and ability, 
is the support of the activity of the worlds, 
is very worshipful (of Vishnu), and 
who incarnates with his full potency (with no diminution);

>in his first avataara, carried the message of LordRaama (as Hanuman),

>destroyed a fearsome army in his second(as Bheemasena) and
