एवं प्रवर्तितं चक्रं नानुवर्तयतीह यः।
अघायुरिन्द्रियारामो मोघं पार्थ स जीवति।।3.16।।

For being the cause of vegetation growing clouds are known as parjanya or rain bringers . Actions are performed due to yagna or worship and all actions flow from and towards the Supreme as Lord Krishna is omniscient and omnipresent. Even though He is eternal He can be known by his aksara potency known as the Vedic scriptures. Yagna is performed by sound, sound vibration is an attribute of all creatures who in turn eat food that was produced by rains falling from clouds manifested by the power of the sun. This is the cycle of yagna that the Supreme Lord is eternally established in. This cycle was set in motion at the dawn of creation by the grandsire Brahma. Whoever does not maintain and perpetuate this cycle which is beneficial to all created beings becomes sinful and degraded and performs activities counter productive to the perseverance of all life and must suffer in the darkest regions of the hellish planets as described in Canto V of the Bhagavat Purana. Now begins the summation. For renunciants yagna or worship may be performed by the recitation and repetition of mantras. For those living as forest recluses the austerities endured are themselves the yagna. For householders the performance of all recommended activities as prescribes in the Vedic scriptures. For brahmacaris the study of the Vedas, celibacy, introspection and service to guru. Fearlessness, charity and the development of atma-tattva or knowledge of the eternal soul are applicable to all of the above. For forest dwellers charity is sharing of food being roots and fruits and wild vegetables to those in need. For the householder charity is donating wealth to worthy recipients in need. But all these actions should be extremely austere and frugal. In the Narada Purana the three activities known as yagna, charity and austerities are prescribed for everyone. The words Brahman denoting the fundamental spiritual substratum pervading all existence and aksara meaning Vedas should be understood to be distinct from each other with the Vedas revealing knowledge of both. having a separate but connected function
