(Vivekachudamani 10) 

May the wise and learned man give up all actions motivated by desires and start the practice of realization of the Self and thereby attain freedom from the bondage of birth and death. 

In the Bhagavad-gītā (13.9) it is stated, janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam: one who is actually advancing must always consider the four principles of miserable life, namely, birth, death, old age and disease. One cannot be saved from all these miseries unless he takes shelter of the lotus feet of the Lord. Śrī Caitanya Mahāprabhu is, therefore, the only shelter for all conditioned souls. An intelligent person, therefore, does not put his faith in any material possessions but completely takes shelter of the lotus feet of the Lord. Such a person is called akiñcana, or one who does not possess anything in this material world. 

As confirmed in the Bhagavad-gītā, simply by understanding constitutional position, appearance and disappearance, one can be immediately elevated to the spiritual kingdom after quitting this present body. Therefore to cross over the ocean of material nescience, an intelligent person takes shelter of Your lotus feet and is easily transferred to the spiritual world.
