Srila Visvanatha Cakravati Thakur indicates we have two lives, or bodies , our receding material consciousness and present body that is tainted with lust ,anger , greed , envy, and illusion and our spiritual personalities and a body  that is  developing side by side . The spiritual sciences of how they develop and decline are given by the six Goswami’s of Vrndavana . A spiritual life is based on the development of a spiritually and mentally conceived spiritual body that is achieved through the process of Sadhana and Ragganuga Bhakti . Our efforts are important and gradually the process of  different yoga practices , such as  karma, jnana , niskarma karma , and trancendental astanga, and ultimately pure Bhakti Yoga transforms one’s consciousness , and the next body is forming side by side of the existing one .

This perfection , however, is achieved only by the krpa ( mercy ) and blessings  of our acayas , the pure devotees, and ultimately the holy name, which is the means and end of spiritual life .
Automatically, our blissful kind nature comes forth more and more, and we free ourselves from the mundane materalistic concepts and always find ourselves absorbed in relishing and remembeing Krishna lila in one form or another.. Mahāprabhu associates demonstrated that, and Mahāprabhu practically teaches it .
So two bodies , one must supercede the other in time . In  so doing  , sometimes the devotees can be initially cold as they defend themselves from mayas’ influences, but they warm up bit by bit until fully on fire in their truely blissful lives .then all their characteristics become  sublime .
