vedastra means-shrawanam keertnam

mā cidanyad vi śaṃsata sakhāyo mā riṣaṇyata | indramitstotā vṛṣaṇaṃ sacā sute muhurukthā ca śaṃsata GLORIFY naught besides, O friends; so shall no sorrow trouble you. Praise only mighty brahman when the keertan-rasa is shed, and say your lauds repeatedly.rigveda

discussion shall yield no result but it is a matter of thought for people believing on science .

gita says...santasbhya atman atmana . dwa suparna sayuja sakhaya from rigveda also can be referred .

jagriti and turiya are two stages of the living body . if a human goes in unconscious state his senses work but the mind is not in the stage of working therefore there exists a  divine conscience stage .

so the jeeva contains two elements as consciousness and conscience  .

gita says...dadami buddhiyogam ten , so buddhiyogam means mindfulness above and over the intelligence .

also here the three stages as upasana , gyan and devotion can be placed at serial no 1, 2 and three .

gyan deepen bhaswata means gyan is not the ultimate but is necessary to be firm in devotion .

Mindfulness and not the copying, suiting to our living to know the absolute truth .
sun is a truth but still not known exactly so determination about the absolute truth as brahman .

Jehi ke jehi par satya sanehu , so tehi milayi na kachhu sandehu...ramcharitmanas

i dont know if it is right ? scientifically it is wrong .
but if it is right then the gita shloka of removing the old clothes and rigveda mantra of the souls playing on top of the tree is correct .

Do the devas exist and where they live ,in earth or are celestial ?
