My 2-year-old son A, one fine day,
A (out of no where) : Mumma, how to do dhyaan mudra? Please do it for me
Me : ok here you go (and now you can see my son's picture doing dhyaan mudra, above in this post)
And then he said, 'family meditation time' ... And we both did Om chanting, Gayatri Mantra and Maha Mrityunjaya Mantra chanting together.
