2. Verily, these have Conception as their union-point, have Conception as their soul, are established on Conception. Heaven and earth were formed through Conception. Wind and space were formed through Conception. Water and heat were formed through Conception. Through their having been formed, rain becomes formed. Through rain having been formed, food becomes formed. Through food having been formed, living creatures (_prāṇa_) become formed. Through living creatures having been formed, sacred sayings (_mantra_) become formed. Through sacred sayings having been formed, sacred works (_karma_) become [per]formed. Through sacred works having been [per]formed, the world becomes formed. Through the world having been formed, everything becomes formed. Such is Conception. Reverence Conception.
