Siva resides in sivalokha, Maheswara resides in maheswara loka, Rudra resides in Kailasam.- All three are different lokalu (From siva,  maheswara emered, From maheswara, rudra emerged, From rudra, visnu emerged, From visnu, brahma emerged)- But Maheswara and rudra are forms of siva as said by siva having same rupam. Brahma has life of 100 years (36,000 Kalpas), Vishnu has a life of 360 Brahmas life, Rudra has a life of 360 Vishnus life, Maheswara has a life of 360 Rudras life, sadasiva has unlimited life(No end to his life)- This strusti is unlimited (anantha brahmandalu). it has unlimited siva lokas(anantha siva lokalu).

Brahmin is the one who has Gunasilalu, who speaks truth, who has dhaya, who has tapasu, who has suchi, ahimsa, who has gnanam, etc (Anyone who has these qualities is the brahman based on veda dharmam to count papa punyalu irrespective of  any caste).

Guru is the one who got pavitrata by speaking always truth(Not what he says truth) and having purity in inner sense(Not what he/she appears to outside) and having true knowledge(How the universe formed,  what is real dharma, what is the saramsam of vedam, knowing about ultimate god, Who am i actually, etc) is only the guru. -Satyamuche pavitramaina anthakarana galavadu, gnani ayinavadu matrame guruvu. 

There is no hard rules in dharma. It is difficult to explain also dharma. what you feel is also may not be dharma. What i feel also may not be dharma, You may not be correct in judging others based on what you see, I may not be correct in judging others based on what i see. But trusting swadharmam is always good than paradharam. 

Hence live without fear of God or without fear of brahman or without fear of guru.
