Those are the words of our Guru Saint Ramalingar.
First of all, it has to be followed scrupulously one and all.
No one should has a second thought either this is to be followed first or the next one.
As a Sanmarga Saadhagar, no one can prioritise one among another.
Every aspirant sanmargi has to fight against killing as well as hunger.
Compassion (Tamil – Jeevakarunyam) is the first step to get Mukthi.
To get blissful life, one has to acquire Arul.
This is the key to go to the God Almighty’s Fort. Only through the activities of compassion
(Tamil – Jeevakarunyam), this goal has to be achieved and not through any other way.
(1) Searching for the God Almighty’s real status and position –
(2) knowing the position of the human being –
(3) living with compassion not giving any trouble to the other living beings
By strictly following the above 3, every sanmargi will get the following by the Grace of God
Almighty.
Get the age of Biramman.; Vishnu, Rudhran; and By Bramha Gnanam, can get everlasting Swarna
Dhegam; and will become God Almighty.

Fight
against hunger :: Fight against killing
Saravanananda Swamigal has written as follows:
It is this higher aspect of every religion to which Saint Ramalingar gives prominence.
He holds compassion as the basis of higher spiritual experiences. According to him he who loves best serves best.
The Saint emphatically declares that love for God will develop in the human minds only and not in other creatures.
When man develops compassion towards his fellow beings, he is said to prepare the ground for Divine Grace.
Without Divine Grace, abiding love for God is not possible. The Saint has used the term “Jeevakarunyam” to denote profound compassion.
It is said giving importance to this subject he has dealt with the subject in seven parts but at present only three of them are available.
Compassion is the fundamental trait of the character of the Saint. This factor is apparent from his poetic appeals to the Almighty.
There are two aspects for the compassionate service.
They are:
1) Doing good to fellow beings, when they suffer from hunger, thirst, disease, ignorance,poverty and fear.
2) Refraining from killing and taking flesh.
As regards the first, he puts more stress on relieving hungry from hunger.
If one pursues the virtue of
relieving one from hunger, it is the supreme help
.
The other kinds of help can be easily rendered by anybody else, as they are supplementaries and sustain the life for some more time
.
The Saint insists that one should give help to all souls with his earned money and through his own physical labour.
When this is not possible, he should at least pray for them.
He insists on family men of low income to be prudent enough in spending money for feeding their own family as well as others who may happen to approach them for food. He thus advocates prudence and thrift.
He not only dissuades the rich from spending money unscrupulously on a grand style during their family ceremonies like marriages and other rituals. He persuades them to feed the needy instead.
His suggestion is that anybody can do this according to his capacity.
He deplores that rich people when they are jubilant and move pompously in high spirits at grand dinners and ostentations music, and dance performances, normally do not relish the sight of a poor, hungry, meek human creature waiting anxiously nearby for a mouthful of food.
It is a practical experience gained by the Saint himself as revealed in one of his poems.
He equally deplores and condemns the act of the pious people in ignoring the poor and destitutes.
The so called great man can do so many wonders like transforming a male into a female, but all such acts done by them without compassion are mere tricks to hoodwink the public and they cannot be termed as “Gnani”
He himself sets as example for the selfless service, indeed it was his motto.
In one of his poems, it is said that he realized God only through this compassionate service and the consequent experience of Grace-light.
We shall now deal with the other aspects of the compassionate service preached and practiced by the Saint.
It is the act of Non-killing and not taking flesh.
He condemns chiefly the sacrifice of life performed in the name of Gods of various types and names.
This sort of killing under the garb of religion is an age-old practice.
Every village deity was said to be appeased by the sacrifice of poor cattle and poultry.
This has spread all over the country. People used to eat what they killed in the name sacrifice under the misconception that it is a gift received from the God.
In modern society, this evil practice has grown by leaps and bounds.
People have been advised to take flesh for health reasons as if they are associated with strength and valour.
The Saint took cudgel against this practice and that of killing. Even from his boyhood, he wished the people to wean away from the act of killing and flesh eating.
For this he formulated the unique path which he called as Samarasa Suddha Sanmarga Sangam meaning the path of virtue to establish non-killing and as an unique one to be accepted by all religions.
It will suffice to say here that he was against even hunting of wild beasts.
As regards flesh-eating, he is very harsh aginst flesh eaters.
According to his theory, flesh eating involves killing the innocent. He describes fleshy food as an inducement for the developments of lower tendencies.
In giving reason for his description, he says that the mind of the flesh eaters cannot at all sense the inner self, and consequently the realisation of God's Eternity will be quite impossible.
With copious reasons, the Saint has advocated his complete faith in vegetarianism, as the right path to realise the Reality.
Nowadays, more westerners, who were addicted to taking non-vegetarian food, are slowly turning towards vegetarianism.
Perhaps the prophecy of the Saint has come true in as much as programmes are being arranged annually by several organisations in ln the line of teachings of the Saint to achieve the goal.
Numerous scientists have now come to the conclusion that vegetarian food is more conducive to health, and it nourishes the body with much strength.
It is hoped in the interest of all, the present world will reap the best of the consequences.

What you have qouted as Swami Saravananda said, is actually conveyed by our Andavar Vallalar istelf in his Jeeva Karunya Discipline books.
He may just highlighted those selected points... That is it.
