A bakthan asked his guru about vaishnava lakshnam and his guru commented about it in the following way:

“kokai pol iruppan kozhiyai pol iruppan
Uppai pol iruppan ummai pol iruppan”

Let’s see Sri Sri's comments on this.

Kokai pol iruppan - A pure vaishnavan will be like swan

Purport:
Swan will be waiting in the shores of river searching for its food (fishes). Even though the swan gets so many small fishes to eat, it will leave them go and will catch, only when it gets the biggest and finest fish. Likewise though the Vaishnavan has so many options, he will catch only the holy feet of Lord Ranganathan/Krishnan.


Kozhiyai po iruppan – A pure vaishnavan will be like a hen.

Purport:

The Hen takes its food (i.e. grain) from the ground only; though it takes from ground, it carefully picks up only the grains and not the other waste in the ground. Likewise though we have many options a vaishsnavan will always pick up only ranganathar/Krishnan as his choice.

Uppai pol irruppan – A pure Vaishnavan will be like salt.

Purport:

Though we have different varieties of food with different flavors, a food without salt is will never be tasty or it will not be preferred. Likewise though there are so many kirtans, songs or bajans a vaishnavan will never be satisfied unless it is Krishna kirtan/Krishna bajan.


Ummai pol iruppan- A pure Vaishnavan will be like you.


Purport:

Though you have learnt so many things, you have devotion, guru bakthi and all Vaishnava qualities; still you are asking me (the acharya) about the qualities of a Vaishnavan without feeling pride about you qualities. This is a main quality of Vaishnavan.

Listening to the glories of God (Hari katha) adds beauty to the ears and not earrings.
