Realisation of love can never come so long as there is the least desire in the heart, or what Shri Ramakrishna used to say, attachment for Kâma-Kânchana (sense-pleasure and wealth). In the perfect realisation of love, even the consciousness of one's own body does not exist. Also, the supreme Jnana is to realise the oneness everywhere, to see one's own self as the Self in everything. That too cannot come so long as there is the least consciousness of the ego (Aham).
Swami VivekanandaEka-Nishtha or devotion to one ideal is absolutely necessary for the beginner in the practice of religious devotion.
Swami VivekanandaIn the world take always the position of the giver. Give everything and look for no return. Give love, give help, give service, give any little thing you can, but keep out barter. Make no conditions and none will be imposed on you. Let us give out of our own bounty, just as God gives to us.
Swami Vivekananda
