Without much bother, if one simply keeps a picture of Sri Caitanya Mahaprabhu at home and chants Hare Krsna, then one will realize God. Anyone can adopt this simple method. There is no expenditure, there is no tax, nor is there any need to build a very big church or temple. Anyone, anywhere, can sit down on the road or beneath a tree and chant the Hare Krsna mantra and worship God.Srila Prabhupada, quoted in
