Second stanza: Bhaja sadhu - samagamam.
Who is Sadhu? A sadhu is a person or a group of people whose company drives you to become better, inspiring you to make positive changes and progress.
Bhaja sadhu samagamam - seek the company of a sadhu and try to be in their company or in the company of people like them as often as possible.
So, look for a company of good people.
What is this advice based on? In ontopsychology (https://ontopsicologia.org), there is such a concept as a semantic field, which is a kind of natural information field, thanks to which one living organism, being near another, can capture biological information emanating from its neighbor. Each team has its own semantic field, and when you are in it, in addition to what is spoken, you also perceive what is meant non-verbally.
Being around people, you perceive and, to a certain extent, copy their qualities. Therefore, if these are good qualities, you will become better. This means that you will feel good when you are in a company with a good semantic field (satsanga).
Third stanza: Kuru punyam ahoratram. Do virtuous deeds day and night.
Ahoratram. Aho is the time from dawn to dusk. Ratram - from dusk to dawn. Do worthy deeds both day and night. During the day, I can do something useful for the world, for society. But what about the night? At night I sleep. So am I wasting my time? But it says: do it both by day and by night. While the body is resting, something constructive has to be done. How can you do something good at night?
The thing a person was focused on before going to sleep (movie, computer game, book, event) continues to be processed by their mind during sleep. This is because our mind can be programmed. Therefore, it is essential to meditate before bed and, when falling asleep, repeat the mantra. As a result, when you fall asleep, the mantra continues to sound in your mind, and in the morning, it seems as if you were doing spiritual practice all night, meditating. Therefore: Kuru punyam ahoratram.
Do virtuous deeds day and night.
Chanting a mantra is one of the most virtuous deeds. When you chant a mantra, you radiate positive energy. This energy fills the world. It also fills your own mind. You and the atmosphere around you are changing for the better. So meditating before bed is a very, very virtuous act. Simultaneously, instead of wasting eight hours, you use your sleep hours as constructively as possible.
