Why is daily sadhana important?
Why is Sandhyavandana important?
Why is daily knowledge of panchang important?
What is the reason behind control of every single aspect of life in Hinduism?
Slow thread.

Sandhyavandana done daily will take you around 12 minutes. Over 10 years, done everyday, that’s 365 x 10 x 12 minutes 43,000 minutes of sadhana. Over 40 years and for those doing more malas of Gayatri, it’s way beyond.
What’s the power of that sadhana.

It takes around 3-4 months to get into a daily routine for sadhana.
That is the hardest part. Once done, the power of a simple sadhana like Sandhyavandana once or passes 10 year mark can completely nullify almost any basic kritrima attack of spirits.

A Brahmana who does 11 malas of Gayatri a day can develop his mental power to such an extent that almost anything is possible.
The mantraraja of all mantras is Surya Gayatri... Tantra attacks and all that stupidity can’t come near that practitioner...

A Brahmana who holds Gayatri in his hrdaya (what happens after 10 years or so) becomes competent to hold the power of the mantras within the body almost instantaneously...
You don’t need to believe me. Those who do it know it.
