The word "varen" means, "I will come". But it is used to mean the exact opposite, "I will leave."
To go" suggests "to go away for ever to heavenly abode", or "to attain the lotus feet of Rama". So, people say, "Varen", to suggest, when they are taking leave, that they will go now, but they will always come back.
