# What is the source of this sloka mentioning gravity?

What is the source of this sloka which mentions gravity?

aakrishta-shaktishcha mahi tvayaa yat
kha-stham guru svaabhimukam svashaktyaa/

aakrishyate tat patatiti khe
same samantat kva patatviyam khe//

(Reference : Jnani-Guru, Paramahansa Nigamannanda Sarasvati, Sarasvata Math, page 7).

meaning: The earth has attraction-power and therefore it attracts heavy things from up above. So the things fall on the earth. Otherwise what falls what on void?

• Ok so it is not Janani (mother) right? also can you add the translation too so that others will know that it is related to gravity? Commented Mar 6, 2019 at 16:20
• This is only a partial and maybe incorrect translation. For example, the first line says: 'Mahi (Earth) obtained the attraction power from you'. Commented Mar 6, 2019 at 18:35
• @user1952500 no. mahi is in samvodhana

• I was referring to `tvaya yat` which means `from you`. Do you have a prose order for this? Commented Mar 6, 2019 at 18:54
• @user1952500 'tvaya yat' can never mean 'from you'. Do u know sanskrit at all :)

It's from Goladhyaya of Siddhanta Shiromani, a work of Bhaskaracharya (a great mathematician and astronomer lived in 12th century) on astronomy.

Siddhanta Shiromani has four parts on particular subject/area:

1. Leelavati - Arithmetic
2. Bijaganita - Algebra

The verse quoted in question is from Goladhyaya.

You can read Goladhyaya in Sanskrit at Internet Archive. Quoting page-30 from book for reference (Indicated the verse with box):

Quoting the text from Sanskrit Wikisource:

यथोष्णताफनलयोश्च शीतता विधौ ङतिः के कठिनवमश्मनि ।
मरुच्चलो भूरचला स्वभावतो यतो विचित्रा बत वस्तुशक्तयः। ५॥

आकृष्टिशक्तिश्च मही तया यरखस्थं गुरु स्वाभिमुखं स्वशक्या ।
आकृष्यते तपततीव भाति समे समन्तात् पतत्वियं खे ॥ ६ ॥

IAST of the emphasized verse is:

ākṛṣṭiśaktiśca mahī tayā yarakhasthaṃ guru svābhimukhaṃ svaśakyā ।
ākṛṣyate tapatatīva bhāti same samantāt patatviyaṃ khe ॥ 6 ॥

• Excellent work.
