Ramakrishna

Have passionate love for God. 

One of  Brahmo songs says:

O Lord, is it ever possible to know Thee without love,

However much one may perform worship and sacrifice?

Pray to God in secret and with yearning, that you may have that passionate attachment and devotion to Him. Shed tears for Him. 

A man sheds a jugful of tears because his wife is sick or because he is losing money or because he is worrying about getting a job. But tell me, who ever weeps for God?’

- Ramakrishna
