Dada Bhagwan said this quote
“ In saying the word ‘Sachchidanand’ [sat-chit-anand, eternal knowledge and vision leading to bliss], it has great ‘effect’. There is an ‘effect’ even when it is said without the understanding [of it’s meaning]. When it is said with the understanding, there is tremendous benefit. Saying these words produces vibrations and everything churns. Everything is ‘Scientific’. ”
