24. If those beings have never before had that wish for
their own sake even in their dreams, how could they possibly have
it for the sake of others?
25. How does this unprecedented and distinguished jewel, whose
desire for the benefit of others does not arise in others even for
their own self-interest, come into existence?
26. How can one measure the merit of the jewel of the mind, which
is the seed of the worlds joy and is the remedy for the worlds
suffering?
27. If reverence for the Buddhas is exceeded merely by an
altruistic intention, how much more so by striving for the complete
happiness of all sentient beings?
28. Those desiring to escape from suffering hasten right toward
suffering. With the very desire for happiness, out of delusion they
destroy their own happiness as if it were an enemy.
29. He satisfies with all joys those who are starving for happiness
and eliminates all the sorrows of those who are afflicted in many
ways.
30. He dispels delusion. Where else is there such a saint? Where
else is there such a friend? Where else is there such
merit?
those famous teachings are from one of the remarkable teacher of
india
shantideva

next we shall take a look at another illustrious teacher of
india
nagarjuna
Very few details on the life of Nagarrjuna are known, although many
legends exist. He may have been born in South India, probably near
the town of Nagarjunakonda in present day Andhra Pradesh. According
to traditional biographers and historians such as Kumarajiva, he
was born into a Brahmin family, but later converted to Buddhism.
This may be the reason he was one of the earliest significant
Buddhist thinkers to write in Sanskrit rather than Pali or Buddhist
Hybrid Sanskrit.

en.wikipedia.org/wiki/Nagarjuna
From studying his writings, it is clear that Nagarjuna was
conversant with the Nikaya school philosophies and with the
emerging Mahayana tradition. If the most commonly accepted
attribution of texts (that of Christian Lindtner) holds, then he
was clearly a Mahayanist, but his philosophy holds assiduously to
the canon, and while he does make explicit references to Mahayana
texts, he is always careful to stay within the parameters set out
by the canon.

Writings
There exist a number of influential texts attributed to Nagarjuna,
although most were probably written by later authors. The only work
that all scholars agree is Nagarjuna's is the Mulamadhyamakakarika
(Fundamental Verses on the Middle Way), which contains the
essentials of his thought in twenty-seven short chapters. According
to Lindtner the works definitely written by Nagarjuna are:
Mulamadhyamakakarika (Fundamental Verses of the Middle Way)
Sunyatasaptati (Seventy Verses on Emptiness)
Vigrahavyavartani (The End of Disputes)
Vaidalyaprakarana (Pulverizing the Categories)
Vyavaharasiddhi (Proof of Convention)
Yuktisastika (Sixty Verses on Reasoning)
Catuhstava (Hymn to the Absolute Reality)
Ratnavali (Precious Garland)
Pratityasamutpadahrdayakarika (Constituents of Dependent
Arising)
Satrasamuccaya
Bodhicittavivarana (Exposition of the Enlightened Mind)
Suhrllekha (To a Good Friend)
Bodhisambhara (Requisites of Enlightenment)
There are other works attributed to Nagarjuna, some of which may be
genuine and some not. There is evidence for a second, later,
Nagarjuna who was the author of a number of tantric works which
have subsequently been incorrectly attributed to the original
Nagarjuna.
It is worth noting that Lindtner considers that the
Mahaprajnaparamitopadesa, a huge commentary on the Large
Prajñaparamita not to be a genuine work of Nagarjuna. This is only
extant in a Chinese translation by Kumarajiva. There is much
discussion as to whether this is a work of Nagarjuna, with some
original comments by Kumarajiva, or an original work by Kumarajiva
based on the philosophy of Nagarjuna.
