The worshipers of Lord Krishna, claim no allegiance to any particular religion, but only continue developing pure, unalloyed bhakti, love of God, through the practice of devotional service, bhakti-yoga. When this fully manifests as prema, such a pure relationship becomes so intense that there is no awareness of anything else. In this pure consciousness, there is no question of being Hindu, Muslim, Christian, Jewish, or being affected by any other distinction. There is only God and the lovers of God on the spiritual platform, all of whom are absorbed in sublime and boundlessly ecstatic, loving exchanges.
The Supreme is waiting for us to return to our spiritual position to engage in these spiritual activities. How long it takes for us to return to our spiritual home simply depends on how long we allow ourselves to be influenced or controlled by the material impulses and desires which bind us to this material existence. We should not feel that we are so sinful or fallen that we have no hope for developing our spiritual relationship with the Supreme, for He is always waiting for His lost servants. But we have to begin to show that we want to return to Him by rising above bodily identifications and realizing the science of the soul: our real identity.
The essence of this portal is pure spiritual identity and spiritual experience that we share with Lord Krishna, the only Supreme Being of this Universe. This spiritual identity is the underlying principle of unity amongst all living entities. Re-awakening this identity and love is the ultimate purpose of this portal. And this is most easily attained through the process of bhakti-yoga, the yoga of love of God.

The Narayana Kavacham occurs in chapter eight of the sixth skanda of Bhagavada Purana. It is an Armour to protect ourselves from our enemies seen and unseen.
Raja Parikshith, the son of Abhimanyu, asks his teacher, Sage Shuka for a means to protect himself from his enemies. Sage Shuka then teaches him the Narayana Kavacham, which was originally taught by Sage Viswaroopa, the son of Thwashtra, to Indra. It is believed that the soul of the man who reads this Kavacha becomes extremely holy and that any one who reads this would be protected by Lord Vishnu.
Sloka 4-11 of this great Stotra give us in detail about the preparations that we should take before reciting this kavacham.
Kavacham's should be learned by a Guru who is well versed in these procedures and chanted under his guidance. If that is not possible, than the kavacham can be recited without performing the Kara and Anga nyasa or simply recite the last four lines.
Before commencing the recital, chant ’Om Namo Naraayanaya’ or ‘Om Namo Bhagvadey Vaasudevaaya’ or your guru Mantra 12 times.
Visualize yourself and/or your loved ones, totally protected. You could ‘see’ them dressed in an armor. You could see them immersed in white or violet light. You could see them in a tube of Light. You could see an impenetrable ring of white Light around them[
