_________________________________
1. the grammatical relation between two syllables in the internal process of the Sanskrit sentence structure, which has its origin in chanting the Vedas with proper accent and rhythm
2. Yoga or yog: It is the natural habit of certain dialects such as Hindi and Gujarati to drop the last letter of a word, but Sanskrit, which is an absolutely scientific language, requires all sounds to be pronounced as written. Hence one who says Yoga is closer to heaven because one has more merits in pronouncing the word correctly. One may choose to say yog casually in one's own dialect, but that is not speaking Sanskrit.
3. the prefix denoting what follows (one of the 22 prefixes in Sanskrit)
4. in standalone usage, shaasanam means rule or teach, as in Buddha shaasanam; when used with the prefix anu it means instruction.
5. in the vowels ri rI, there is a dot under the r as the correct dialectic mark
6. (त्त double tt त्त, त single t and त्त tt)
7. cf. chit universe consciousness as in sat (true nature), cit (universal consciousness), ananda (supreme bliss)
8. prefix ni: as in gacchati go and ni + gacchati to come out.
9. then be in your own form, to visualize your own form, your inner true nature, to be in Samadhi, where there is no movement because all modification of the mind has ceased and be in your own internal form.
