Lord Chaitanya Mahaprabhu said that we are wandering throughout the universe in many species of life, and when we come to this human form of life, if we are fortunate, or if we are fortunate to meet another fortunate devotee, then we can understand what is Krishna. Thus we are immediately relieved from traveling from one body to another and from one planet to another.

While traveling, a living entity becomes fortunate enough to become blessed by the association of devotees and to come to Krishna consciousness, his real life actually begins. This Krishna consciousness movement is giving all wandering living entities a chance to take to the shelter of Krishna and thus become happy.

——Srila Prabhupada
