Twin Birds  [ conscience and consciousness ] with fair wings, knit with bonds of friendship, in the same sheltering tree have found a refuge.
One of the twain eats the sweet Fig-tree's fruitage; the other eating not regardeth only.
 Where those fine Birds hymn ceaselessly their portion of life eternal, and the sacred synods,
There is the Universe's mighty Keeper, who, wise, hath entered into me the simple.
  The, tree whereon the fine Birds eat the sweetness, where they all rest and procreate their offspring,
Upon its top they say the fig is luscious: none gaineth it who knoweth not the Father.

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 ?
