According to Osho, the inability to express overwhelming gratitude and love is natural and even a good sign - the feeling is too deep for words; silence befits it. Still, keep trying: even a few 'drops' in words carry the ocean’s taste and can guide others. Accept wordlessness, speak anyway, and let the song continue.
When love is very big, words get too small—feel it, be quiet if needed, but still share a little because even a little shows the whole.
