Namaste Star Sis.
First of all, if it says Sree Satya Sai Baba products, it would be right from India. Bangalore is Asia's software capital, but it is also a spiritual city of India with various spiritual Guru's having their head quarters in there. Apart from these, Bangalore is also the aroma capital of India having thousands of incense making factories.
I have heard about Nag Champa incense sticks, it is a rave in here, but frankly I personally do not use it (I have used it but never really liked it).
According to our beloved Guru, use of incense is very important in energy balancing and cleansing, so the right "prana" should be produced when it is burned. I am sure there are various kind of incense that can be used, but my personal favourite is called Golden Cobra and Woods. Golden Cobra has been awarded the best herbal sticks here in India and is a great one. Woods is a bit too expensive, and my favourite. At my home I use Woods, at office I use Golden Cobra (because of the increased number burned, it is financially viable for me).
I am not saying you should use the same, neither am I promoting them, but when we use the incense what we need to look for is the proper herbal ingredients if it contains sandal / lavender they are the best cleansing agents. Preferably use ONLY herbal incense since the chemical ones can cause adverse effects in the brain. When we use herbal incense we can dip it in water, make it wet and then burn it, which is found to be extremely effective.
