Relevant rules of God

What is the message given by Adi Shankara which is relevant even today? God lovingly reminds us today.
When Adi Shankara was residing at Varanasi with his pupils, he came across a scholar, who was immersed in complicated rules of grammar. When asked why he had taken up this intensive study, he replied that it would easily fetch him a few pieces of silver. "If I am designed a pandit, I can go to the home of some big zamindars (landlords), and hope to receive gifts and offerings from them for the livelihood of my large family," he said. Shankara then advised him appropriately and charged him with self-confidence and courage. Returning to his hermitage, Shankara wrote a verse summarising the advice he gave the poor scholar thus: Bhaja Govindam, bhaja Govindam, bhaja Govindam, moodha mate. Samprapte sannihithe kale, nahi nahi rakshati dukrun karane (Praise God, Praise God, Praise God, you foolish mind! When death approaches, rules of grammar cannot save you). The study of these verses and the inspiration derived from them will promote discrimination and detachment, and thus, prepare the mind for the vision of the Supreme power of the Universe.
Human beings always think
" What will people say ???"
Presence of God is everywhere but the person who  always worship can feel only because he has your heart and feeling for his God. God has given us every Breath and second for living a life of human beings.
