Dada Bhagwan said this quote
“ What is the difference between aradhana (worship) and bhajana (to be one with)? Aradhana (worship) means the attention will go over and over again there, and bhajana (oneness) means continuous engrossment. One is to do aradhana (worship) and bhajana (oneness) for only one’s own Self; everything else will carry on naturally. ”
