Dear Ganapati!
My simple methods..
Deva Yagyam -
RECITNG SLOKAS OR JUST THINKING ABOUT DIVINELY ACTS OF GODS - For this you need to read scriptures or must have some heard ramayana,mahabharata etc... from competent puranic readers.
Pitru Yagyam -
Since our foreparents are the cause for our bodily existence. we do namaskarams or simply think about the chance they give us to be here as human. If deceased then each day ATLEAST remember them.
Rishi Yagyam
Invite with namaskaram the learned pandits, and respectfully question them on the spiritual quest. care should be taken that they interpret only what is told in vedas , not their own stuff. So seek for proffessionel learned help.
Manushya Yagyam
Help the people out of people in whatever way possible. To give food for strangers before taking lunch was in vogue in old India. If you cannot practise this atleast put some cents or dollar for feeding poor and regularly donate.
Bhoota Yagyam.
In India we practice still to give food to birds before eating. Any thing beneficial done to animals (here not your pet) is bhoota yagyam.
Simply anyone can and should practise as this will remove many obstacles in a spiritual seeker.
