Dada Bhagwan said this quote
“ Shukladhyan (pure contemplation of the Self, the Soul) is the direct cause for moksha (liberation). Dharmadhyan (auspicious contemplation; to hurt no one, give happiness to others) is the indirect cause for moksh (liberation). Artadhyan (inner mournful contemplation that hurts the self) is a cause for a birth in animal life form (non-human). Raudradhyan (wrathful contemplation that hurts the self and others) is a cause for a life in hell. ”
