If your consciousness is absorbed in Krishna, you are always a sanyasi.
Although the mind may work imperfectly at the time of death, Krishna gives a devotee shelter at His lotus feet. Therefore, when a devotee gives up his body, the mind does not take him to another material body. Rather, Krishna takes the devotee to that place where He is engaged in His pastimes. One’s consciousness, therefore, must always be absorbed in Krishna and then one’s life will be successful. Otherwise, the mind will carry the soul to another material body.
The Devotee's Mood : Everything is for Krishna, Nothing for me and whatever comes, its Krishna's mercy, Krishna's Prasad.
Krishna Consciousness means being conscious of Krishna's mercy at every single moment.
It is not that the moment one comes to the platform of devotion, he immediately achieves his perfection. Gradually by performing devotional service he comes to the platform of perfection.
If we will follow four regulative principles then sins will not be able to touch us.
