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).
